Question

A ball is placed on a ramp and allowed to roll to the bottom onto a table. The velocity of the ball is determined by how far the ball lands from the edge of the table on the floor below. The kinetic energy at the bottom of the ramp is significantly less than the gravitational potential energy change from the top to the bottom of the ramp. What is most likely the reason for this discrepancy?

Choices

Choice (5)Response

a.

The transfer of thermal energy to the ball from the ramp

b.

The work done by the gravitational force on the ball

c.

The work done by the normal force on the ball

d.

The work done by the friction force on the ball

e.

All of the above
