Adifferent group of students decided to do this experiment by

measuring the motion of an object that is sliding down a ramp (instead

of falling) because they were worried that the detector would not

capture the falling motion very effectively. when they compared the

initial gravitational potential energy to the final kinetic energy, they

found that energy was not conserved; some energy was lost.

after discussion, they decide that friction between the ramp and the

object is a likely problem. they all make suggestions for how to change

the experiment to make energy conservation more likely. given what!

you know about friction, which of these suggestions from group

members is likely to reduce the energy lost to friction? select all that

apply.
