Choose the best answer for each question from the choices below. Be clear about which answer you are circling-none of this trying to circle 2 answers and be sloppy so I'll just count it correctC And then explain why you have chosen the answer you chose. Good Luck!!!
1. Newton's 3 Law states...
a. Objects in motion stay in motion and objects at rest stay at rest
b. Force is equal to mass times acceleration
c. For each action there is an equal and opposite reaction
Why???
2. An archer shoots an arrow. The action force is the bowstring against the arrow, The reaction force is... a. Air resistance against the bow
b. Arrow's push against the bowstring
c. Grip of the archer's hand on the bow
Why???
3. A player catches a ball. The action force is the impact of the ball against the player's glove. The reaction force is...
a. The force the glove exerts on the ball
b. The player's grip on the glove
c. The friction of the ground on the player's shoes
Why???
4. A player hits a ball with a bat. The action force is the impact of the bat against the ball. The reaction force is...
a. The grip of the player's hands on the ball
b. The air resistance on the ball
c. The force of the ball against the bat
Why???
5. A baseball player bats a ball with a force of 1,000 N. The ball exerts a reaction force against the bat of...
a. Less than 1,000 N
b. More than 1,000 N c. 1,000 N
Why???
6. A person is attracted toward the center of the Earth by a 500 N gravitational force. The force that the Earth is attracted toward the person is...
a. 500 N
b. Much less than 500 N
c. Much more than 500 N
Why???
1. The correct answer is c. For each action there is an equal and opposite reaction. This is Newton's third law of motion, which states that for every action force, there is an equal and opposite reaction force. This means that the forces exerted by two objects on each other are always equal in magnitude and opposite in direction.
2. The correct answer is b. Arrow's push against the bowstring. In this scenario, the action force is the bowstring pushing against the arrow, and the reaction force is the arrow pushing against the bowstring. This is because every action force has an equal and opposite reaction force.
3. The correct answer is a. The force the glove exerts on the ball. In this case, the action force is the impact of the ball against the player's glove, and the reaction force is the force exerted by the glove on the ball to stop its motion. Again, these forces are equal and opposite according to Newton's third law of motion.
4. The correct answer is c. The force of the ball against the bat. When the player hits the ball with a bat, the action force is the impact of the bat against the ball, and the reaction force is the force exerted by the ball against the bat. This reaction force is what causes the ball to bounce off the bat.
5. The correct answer is a. Less than 1,000 N. According to Newton's third law of motion, the reaction force exerted by the ball on the bat is equal in magnitude but opposite in direction to the force exerted by the bat on the ball. Therefore, the reaction force exerted by the ball on the bat is also 1,000 N.
6. The correct answer is a. 500 N. According to Newton's third law of motion, the force of gravity is an example of an action-reaction pair. The person is attracted towards the center of the Earth with a force of 500 N, and the Earth is attracted towards the person with an equal and opposite force of 500 N.
