Force, motion, and energy review

What is the force that slows down or eventually stops an objects motion?

• Gravity

• Push

• Motion

• Friction

A student uses a spring scale to pull a 50-gram block horizontally across a wood desk. Then the student pulls the block the same distance across surfaces of carpet, sandpaper, and glass. Which question is this investigation most likely designed to answer? (5.6D)

• How do block of different sizes react to force?

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

• How do blocks affect spring scales?

• How does the mass of a block change when it is pulled across a desk?
