Front

What is the force that slows down or eventually stops an object's motion?

Back

Friction

Front

A student uses a spring scale to pull a 50-gram block horizontally across a wood desk, carpet, sandpaper, and glass. What is this investigation designed to answer?

Back

How do different surfaces affect the amount of force needed to move a block?

Front

What is most likely Step 3 in the student's experiment to study the formation of craters using marbles and a pan of flour?

Back

Drop the same marble from different heights into the pan of flour

Front

What other piece of equipment would be most useful for testing the force of a spring using a spring launcher and four spheres with the same diameter but different masses?

Back

A meterstick to measure the height each sphere reaches after the sphere is launched

Front

Which experiment will best determine how friction affects the speed of a rolling object? Options: Roll 3 objects of various sizes across the floor., Roll 3 objects of equal size from various heights across the floor., Roll 3 objects of equal size across 3 different types of surfaces., Roll 3 objects of equal size from equal heights across the floor.

Back
