Drag and drop the vocabulary word with it's matching definition. This is a force which resists all motion. This is an attractive force between any two objects due to mass. For every action, there is an equal and opposite reaction. This is the SI (metric) unit of force. A law of motion that states that an object at rest stays at rest and one in motion stays in motion. This says the acceleration of an object increases by the force applied to it, and decreases based on its mass. In the second law of motion is is Mass X Acceleration the ability to apply a change in velocity on a given object. This is what causes acceleration two forces acting opposite eachother. Options are Newton's Second Law, Newton's First Law, Force, Newton's Third Law, Gravity, Unbalanced Forces, Friction, Newton.

Newton - The SI (metric) unit of force.
Okay so this is a force which resists all motion goes with force?
Yes, that is correct. "A force which resists all motion" would match with the term "force."
does his is an attractive force between any two objects due to mass go with gravity
Yes, that is correct. "An attractive force between any two objects due to mass" matches with the term "gravity."
does For every action, there is an equal and opposite reaction go with newtons third law
Yes, that is correct. "For every action, there is an equal and opposite reaction" is the definition of Newton's third law.
does This is the SI (metric) unit of force go with newton
Yes, that is correct. "This is the SI (metric) unit of force" matches with the term "newton." The newton (N) is the SI unit of force.
does A law of motion that states that an object at rest stays at rest and one in motion stays in motion go with newtons first law
Yes, that is correct. "A law of motion that states that an object at rest stays at rest and one in motion stays in motion" corresponds to Newton's first law of motion.
does This says the acceleration of an object increases by the force applied to it, and decreases based on its mass go with newtons second law
Yes, that is correct. "This says the acceleration of an object increases by the force applied to it, and decreases based on its mass" matches with Newton's second law of motion. The second law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
does In the second law of motion is is Mass X Acceleration the ability to apply a change in velocity on a given object. go with friction
No, the statement "In the second law of motion is Mass X Acceleration the ability to apply a change in velocity on a given object" does not match with friction.
The correct match for that statement is force. In the second law of motion (Newton's second law), the equation is Force = Mass X Acceleration, which represents the ability to apply a change in velocity on a given object. Friction is a separate concept related to the resistance encountered when objects move against one another.
In the second law of motion is is Mass X Acceleration the ability to apply a change in velocity on a given object does this go with friction or unbalanced forces
This statement does not match with either friction or unbalanced forces. The statement "In the second law of motion is Mass X Acceleration the ability to apply a change in velocity on a given object" accurately describes Newton's second law of motion, where force is calculated by multiplying mass and acceleration. It does not directly correlate with the definitions of friction or unbalanced forces.
In the second law of motion is is Mass X Acceleration the ability to apply a change in velocity on a given object does this go with newtons second law or friction
The statement "In the second law of motion, Mass X Acceleration is the ability to apply a change in velocity on a given object" matches with Newton's second law of motion. Newton's second law states that the force acting on an object is directly proportional to the product of its mass and acceleration. So, the statement refers to Newton's second law, not to friction.
A stressed out Mom just purchased a cup of Starbucks coffee. The bus she is riding on to work goes around a sharp curve. Even though she holds the cup still, the coffee still splashes out. Which word explains this phenomenon? A. inertia B. density C. friction D. gravity
The word that explains this phenomenon is A. inertia. Inertia is the tendency of an object to resist any change in its motion. In this scenario, the coffee inside the cup wants to keep moving in a straight line due to its inertia, but when the bus goes around a sharp curve, the cup experiences a change in direction, causing the coffee to spill out.
If Sally and Sam both push on a box with a force of 40 N, but in opposite directions, what will happen to the box?
If Sally and Sam both push on a box with a force of 40 N, but in opposite directions, the box will experience an unbalanced force. The resulting motion of the box will depend on the mass and friction present. If there is no friction or if the force of friction is less than 40 N, the box will accelerate in the direction of the larger force. If the forces are equal and opposite, and there is no friction, the box will not move and remain at rest.
Consider the situations below. Which of these is the BEST example of newtons 1st law (inertia)?
A. A tennis player throws the tennis ball into the air for a serve and the ball falls to the ground.
B. You go down a steep hill in a sled and it feels like your stomach is going up into your throat.
C. A bird takes flight from the ground
D. Tom uses a cane to walk across the road
The BEST example of Newton's 1st law (inertia) among the given situations is C. A bird takes flight from the ground.
Newton's 1st law states that an object at rest will remain at rest, and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force. In this case, the bird is initially at rest on the ground, and it requires an external force (the flapping of its wings) to overcome its inertia and initiate flight.
Which newton law is this sentence When riding the bumper cars at the fair, you bump into your friend and your car bounces backwards.
The sentence "When riding the bumper cars at the fair, you bump into your friend and your car bounces backwards" exemplifies Newton's third law of motion.
Newton's third law states that for every action, there is an equal and opposite reaction. In this scenario, when you bump into your friend in the bumper cars, the force you exert on your friend results in an equal and opposite reaction force that pushes your car backward.
Which newton law is this sentence A ball is rolling straight across the floor until Bradley kicks it.
The sentence "A ball is rolling straight across the floor until Bradley kicks it" is an example of Newton's first law of motion.
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant velocity unless acted upon by an external force. In this case, the ball is already in motion, rolling straight across the floor until Bradley applies an external force by kicking it.
Which newton law is this sentence A bowling ball and a baseball both roll across your foot at the same speed. The bowling ball hurts much more.
The sentence "A bowling ball and a baseball both roll across your foot at the same speed. The bowling ball hurts much more" does not relate to any specific Newton's law of motion.
The scenario described in the sentence involves the concept of impulse and momentum rather than a specific law of motion. The bowling ball hurts more because it has more momentum than the baseball. Momentum is the product of an object's mass and velocity, and when the bowling ball collides with your foot, it imparts more force due to its greater mass.
wrong
Apologies for the confusion. The sentence "A bowling ball and a baseball both roll across your foot at the same speed. The bowling ball hurts much more" can be explained by Newton's second law of motion.
Newton's second law states that force is equal to mass multiplied by acceleration (F = ma). In this case, both the bowling ball and the baseball are rolling across your foot at the same speed, which means they have the same velocity. However, the bowling ball has a significantly larger mass compared to the baseball. According to Newton's second law, the force experienced is directly proportional to the mass of an object. Therefore, the greater mass of the bowling ball results in a greater force being applied, causing more pain or discomfort when it rolls across your foot.
Which newton law is this sentence Your car breaks down. As your friends help you push it, it begins to move and speed up.
The sentence "Your car breaks down. As your friends help you push it, it begins to move and speed up" exemplifies Newton's second law of motion.
Newton's second law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In this scenario, as your friends apply a force to push the car, the net force exceeds the opposing forces (such as friction and air resistance), and the car starts to move. As they continue to push with a sufficient force, the car's acceleration increases, causing it to speed up.
Which newton law is this sentence A fireman turns on his hose and is knocked backwards.
The sentence "A fireman turns on his hose and is knocked backwards" illustrates Newton's third law of motion.
Newton's third law states that for every action, there is an equal and opposite reaction. In this scenario, when the fireman turns on the hose and water is ejected with force in one direction, the water exerts an equal and opposite force in the opposite direction according to Newton's third law. This results in the fireman being pushed backwards as a reaction to the force exerted by the water coming out of the hose.
Which newton law is this sentence A soccer ball will not move until a player kicks it.
The sentence "A soccer ball will not move until a player kicks it" exemplifies Newton's first law of motion.
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant velocity unless acted upon by an external force. In this case, the soccer ball is initially at rest, and it will stay that way until an external force, such as a player kicking it, is applied to overcome its inertia and set it in motion.
Which newton law is this sentence F = ma
The sentence "F = ma" represents Newton's second law of motion.
Newton's second law states that the force acting on an object is equal to its mass multiplied by its acceleration. This relationship is mathematically expressed as F = ma, where F represents the force, m represents the mass of the object, and a represents the object's acceleration. According to this law, an object's acceleration is directly proportional to the net force applied to it and inversely proportional to its mass.
A roller coaster begins at the top of a hill. If it accelerates at the rate of 2 m/s and has a mass of 2000 kg, what net force is acting on it? (Force=mass x acceleration)
A. 400 N
B. 0.5 N
C. 1000 N
D. 0.001 N
The net force acting on the roller coaster can be calculated using Newton's second law, which states that force is equal to the mass of an object multiplied by its acceleration (F = ma).
Given in the problem:
Acceleration (a) = 2 m/s²
Mass (m) = 2000 kg
To find the net force (F), we can substitute these values into the formula:
F = mass x acceleration
F = 2000 kg x 2 m/s²
F = 4000 kg·m/s²
The unit for force in the SI system is Newton (N). To convert from kg·m/s² to Newton, divide the value by 9.8 m/s² (acceleration due to gravity):
F = 4000 kg·m/s² / 9.8 m/s²
F ≈ 408.16 N
Rounded to the nearest whole number, the net force acting on the roller coaster is approximately 408 N. Therefore, the correct option is:
A. 400 N
A roller coaster begins at the top of a hill. If it accelerates at the rate of 2 m/s and has a mass of 2000 kg, what net force is acting on it? (Force=mass x acceleration)
A. 4000 N
B. 0.5 N
C. 1000 N
D. 0.001 N
The net force acting on the roller coaster can be calculated using Newton's second law, which states that force is equal to the mass of an object multiplied by its acceleration (F = ma).
Given in the problem:
Acceleration (a) = 2 m/s²
Mass (m) = 2000 kg
To find the net force (F), we can substitute these values into the formula:
F = mass x acceleration
F = 2000 kg x 2 m/s²
F = 4000 kg·m/s²
The unit for force in the SI system is Newton (N). To convert from kg·m/s² to Newton, the value remains the same.
Therefore, the net force acting on the roller coaster is 4000 N. So the correct option is:
A. 4000 N
Matt is walking at 1.25 miles per hour to the east. Jaime is walking at 1.25 miles per hour to the south. Which statement describes the movement of Matt and Jaime?
A. they have the same speed but different velocities.
B. they have different speeds but the same velocity
C. they have different speeds and different velocities
D. they have the same speed and the same velocity
The correct statement that describes the movement of Matt and Jaime is:
C. They have different speeds and different velocities.
Speed refers to the magnitude of the rate at which an object moves, while velocity takes into account both the speed and direction of motion. In this scenario, Matt is moving to the east while Jaime is moving to the south. Even though they have the same speed of 1.25 miles per hour, their velocities differ because they are moving in different directions. Hence, they have different speeds and different velocities.
In which situation would the momentum of a moving object increase?
A. Two forces of equal magnitude act on the object in opposite directions.
B. A force acting in the direction opposite the object’s motion is removed from the object.
C. A new force acts on the object, opposing the object’s motion.
D. A force acting in the direction of the object’s motion is removed from the object.
The correct situation in which the momentum of a moving object would increase is:
D. A force acting in the direction of the object's motion is removed from the object.
According to Newton's second law of motion, the change in momentum of an object is equal to the force acting on it multiplied by the time interval during which the force is applied. Removing a force acting in the direction of the object's motion would decrease the opposing force, resulting in a net force in the direction of motion. As a result, the object's momentum would increase.
Steven is trying out for the position of pitcher on the baseball team. He can throw the baseball fast! The coach has clocked some of his pitches at 85 mph. Some of Steven's friends decided to play a joke on him and replaced one of the baseballs with one that they tampered with. Instead of a mass of 145 grams, the boys added a lead weight so the mass is now 200 grams. Steven winds up and throws. All of the statements describe the possible results of this scenario except one. Which statement is an inaccurate explanation?
A. Steven must throw the new ball with more force in order for it to achieve the same speed as previous throws.
B. Since force equals mass times acceleration, Steven’s throwing force must increase to throw the ball 85 mph.
C. If Steven’s throwing force is constant and the ball’s mass increases, the rate of acceleration will be less.
D. The difference in the mass is not significant and will not affect the force needed to throw the ball 85 mph.
The inaccurate explanation in this scenario is:
D. The difference in the mass is not significant and will not affect the force needed to throw the ball 85 mph.
In reality, the difference in mass does have an impact on the force needed to throw the ball 85 mph. According to Newton's second law of motion (F = ma), the force required to accelerate an object is directly proportional to its mass. As the mass increases, a greater force is needed to achieve the same acceleration. In this case, since the mass of the ball has increased from 145 grams to 200 grams, Steven would indeed have to apply a greater force to achieve the same throwing speed of 85 mph. Therefore, statement D is inaccurate.
