If Object A Exerts a Force on Object B, then Object B Exerts an Equal, Oppositely Directed, and Simultaneous Force on Object A
Newton’s Third Law
For Every Action There is an Equal and Opposite Reaction
If your feet push down on the floor, what does the floor do?
A. NothingB. Absorbs the pushC. Pushes up on your feet, but with less forceD. Pushes up on your feet with an equal forceE. Pushes up on your feet with greater force
Can the floor push up on your feet with a force greater than
your weight?
A. Yes, but nothing will happenB. Yes, you will accelerate up into the airC. No, it always equals your weightD. No, it can only equal or be less than your
weightE. Yes, but only on a planet with stronger gravity
What is the force from that causes a car to accelerate down the road?
A. The engineB. The transmissionC. The pistonsD. The roadE. The tires
What is the force from that causes a swimmer to accelerate across a pool?A. The swimmer’s legsB. The swimmers armsC. The swimmer’s arms and legsD. GravityE. The water
Which force probe will measure the greatest force?
A. The one pulled by the teacherB. The one attached to the ring standC. Both will measure the same forceD. Either one depending on how the teacher pulls
Which force probe will measure the greatest force?
The Earth pulls on the Moon with gravity, causing it to orbit. What does the Moon
do to the Earth?
A. Pulls on the Earth with equal gravity, causing it to orbit
B. Nothing, it is too smallC. Pulls on the Earth with less gravity, having no
effectD. Pulls on the Earth with less gravity, causing
tides
The Earth orbits a point about ¾ of the distance from its center to its surface (not to scale)
The Earth pulls on you with the force of gravity, what is the reaction to this force?A. Normal forceB. You pull on the Earth with an equal force of
gravityC. You pull on the Earth with a smaller force of
gravityD. Nothing, only the Earth has gravity
