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 and object 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 it is mass x acceleration the ability to apply a chance in velocity on a given object, this is what causes acceleration two forces acting opposite eachother. The options are newtons second law, newtons first law, force, newtons third law, gravity, unbalanced forces, friction, and newton.
Force: a push or pull on an object.
Gravity: an attractive force between any two objects due to their mass.
Newton: the SI (metric) unit of force.
Newton's First Law: a law of motion that states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same velocity, unless acted upon by an external force.
Newton's Second Law: a law of motion that states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass (F = ma).
Newton's Third Law: a law of motion that states that for every action, there is an equal and opposite reaction.
Friction: a force that resists the motion of an object.
Unbalanced Forces: forces that are not equal and opposite, resulting in a change in motion.

the acceleration of an object increases by the force applied to it and decreases based on its mass would go with newtons second law?
Yes, that is correct. The statement "the acceleration of an object increases by the force applied to it and decreases based on its mass" is a description of Newton's Second Law of motion.
in the second law of motion it is mass x acceleration the ability to apply a chance in velocity on a given object would it go with force or unbalanced forces
The statement "in the second law of motion it is mass x acceleration the ability to apply a change in velocity on a given object" would go with force. In Newton's Second Law of motion, the equation is F = ma, where F represents force, m represents mass, and a represents acceleration. So, the ability to apply a change in velocity on a given object is related to force according to this law.
this is what causes acceleration two forces acting opposite eachother would go with unbalanced forces then?
Yes, that is correct. The statement "this is what causes acceleration two forces acting opposite each other" is associated with unbalanced forces. When two forces acting on an object are not equal and opposite, they create an unbalanced force that causes acceleration in the direction of the net force.
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. Gravity 2. Density 3. Friction 4. Inertia
The word "Inertia" explains this phenomenon. Inertia is the tendency of an object to resist changes in its motion. In this case, when the bus turns around a sharp curve, the coffee tends to continue moving in a straight line due to its inertia. As a result, it splashes out of the cup, even though the mom is holding the cup still.
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? The both will be perpendicular to both sally and sam, the box will not move, the box will slide toward sally, the box will slide toward sam
If Sally and Sam both push on a box with a force of 40 N but in opposite directions, the box will slide toward Sally or Sam depending on factors such as the friction between the box and the surface it is on. Without any other forces acting on the box, the net force (the vector sum of the individual forces) would be zero, resulting in no motion. However, if there is friction present that is greater in one direction than the other, the box will slide toward the direction with less friction.
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? A. The box will be perpendicular to both sally and sam. B. the box will not move C. the box will slide toward sally D. the box will slide toward sam
B. The box will not move.
