Newton's 3rd Law Practice

Newton's 3rd law says that when two objects interact, the forces between them will be ________ in magnitude

Newton's 3rd law says that when two objects interact, the forces between them will act in ________ directions

A student kicks a soccer ball. According to Newton's 3rd law, what is the "reaction" in this situation

• The soccer ball flies off into the air

• You can hear the soccer ball being kicked

• The soccer ball exerts a force back on the student's foot

• Other students chase after the soccer ball

The spartan shop sign hangs from the ceiling from chain. What forces act on the sign?

• Normal

• Tension

• Gravity

• Applied

• Friction

The spartan shop sign hangs from the ceiling from chain. The earth pulls down on the sign. What is the 3rd law pair with the Earth's force?

• The sign pulls down on the ceiling

• The sign pulls down on the chain

• The chain pulls up on the sign

• The sign pulls up on the earth

A student stands on the floor. While standing on the floor, he pulls down on a weighted cable. What forces act on him?

• Gravity

• Tension

• Friction

• Air Resistance

• Normal

A student stands on the floor. While standing on the floor, he pulls down on a cable attached to weights. If the "action" is him pulling down on the cable, what is the "reaction"

• The weights are lifted up

• He feels tired

• His weight decreases

• The cable pulls him up

A student does the leg press, which involves him pushing on a weighted platform. The force of his press equals the weight of the platform, and the forces act in opposite directions.
Is it correct to say that the applied force and the weight are an example of a Newton's 3rd Law pair?

• Yes

• No

A student drops a basketball onto the floor. According to Newton's 3rd law, why does the ball bounce?

• The student dropped the ball

• The earth pulls the ball down

• The ball presses down on the floor

• The floor presses up on the ball

A soccer ball breaks through a window. How does the force on the window compare with the force on the ball?

• The ball experiences a greater force

• The window experiences a greater force

• The window and ball experiences forces equal in magnitude
