Force Motion Energy

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?

A student designs an experiment to test the force of a spring using a spring launcher and four spheres with the same diameter but with different masses. What other piece of equipment would be most useful for this experiment? (5.6D)

• A graduated cylinder to measure the volume of each sphere before the sphere is launched

• A beaker to collect the spheres after they are launched

• A stopwatch to measure how long it takes to load each sphere on the spring

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