Question

Is this statement true?

"A higher coefficient of friction leads to a higher percentage of energy loss of skaters from the top of a ramp to the bottom."

Answer 1

I think this is true, since more friction causes more thermal energy to be created and since the kinetic energy will be lower near the bottom of a ramp.

Answer 2

i think it is true,

Answer 3

yes. Friction causes a force on the object resisting motion , rolling friction \[\large F _{r}=\mu _{r}*N\]
The force is non-conservative and does work on the object. You see it is proportional to the friction coefficient. So a higher coefficient will be a higher force and more work done.

From the conservation of energy, the total energy loss KE + PE should be equal to the work done from the friction force.
