Newton's third law
False
A bicycle and a parked car have a head-on collision. The force of impact is greater on the bicycle.
road
A force is exerted on the tires of a car to accelerate the car along the road. The force is exerted by the
on the nail and also on the hammer
A high school student hits a nail with a hammer. During the collision, there is a force
3 times as fast
A pair of blocks, one 3 times as massive as the other, are connected by a compressed spring. When the spring is released, the blocks fly apart. Compared to the heavier block, how many times as fast does the lighter block accelerate?
400-N.
A person is attracted towards the center of Earth by a 400-N gravitational force. The force with which Earth is attracted toward the person is
The force the glove exerts on the ball
A player catches a ball. Consider the action force to be the impact of the ball against the player's glove. What is the reaction to this force?
of the exhaust gases on the rocket
A rocket is able to accelerate in the vacuum of space when it fires its engines. The force that propels the rocket is the force
500-N
If you push off the ground with a force of 500-N when you jump upward, what force pushes Earth downward?
gently on you
According to Newton's third law, if you push gently on something, it will push
arrow's push against the bowstring
An archer shoots an arrow. Consider the action force to be the bowstring against the arrow. The reaction to this force is the
larger
An unfortunate bug splatters against the windshield of a moving car. Compared to the deceleration of the car, the deceleration of the bug is
the same
An unfortunate bug splatters against the windshield of a moving car. Compared to the force of the car on the bug, the force of the bug on the car is

Forces always occur
1000-N
If a car hits a tree with 1000-N of force, how much force does the tree exert onto the car?
75-N
If you hit a wall with a force of 75-N, how much force does the wall exert on you?
200-N
Two people pull on a rope in a tug-of-war. Each pulls with 200-N of force. What is the tension in the rope?
For every action there is an equal and opposite reaction
What is Newton's Third Law
The floor
What pushes along you while you walk along the floor?
no, but the force is the same
When a cannon is fired is the acceleration of the cannon and the cannonball the same?
No
When you rub your hands together, can you push harder on one hand than the other?
always true
Whenever an object exerts a force on another object, the second object exerts a force of the same magnitude, but in the opposite direction to that of the first object.
different masses
Why do objects that experience the same amount of force accelerate at different rates?
greater friction
Why is it easier to walk on a carpeted floor than on a smooth, polished floor?
