Students conduct experiments to investigate friction. Which experiment will best test the effect of friction on objects?

• Drop two balls from the same height at the same time

• Roll two marbles on the carpet from the same starting point at the same time and with the same amount of force

• Roll three marbles across three different surfaces from the same starting point at the same time and with the same amount of force

• Release two balls from the top of a ramp at the same time

A change in position-

• movement

• energy

• stop

• friction
