Question

Do the bicycle and rider have energy when they're positioned at the top of the hill? If so, try to explain your answer. (Hint: Compare what happens at the top of the hill to what would happen at the bottom, given the same conditions.)

Answer 1

Yes, the rider and bicycle have energy at the top of the hill. That’s because they move without pedaling when the brake is released. If the rider and bicycle were at the bottom of the hill, just releasing the brake wouldn’t create motion. The rider would need to pedal.

Step-by-step explanation:

This is the sample answer on edmentum.

Answer 2

on the top of the hill there is energy gravitational potential.

Step-by-step explanation:

The energy of a body is the possibility of doing work, in the case of the bicycle on the hill, it has a configuration energy due to being higher than the lower part of the hill.

If we let go of the bicycle it accelerates downwards due to the component of the force of gravity, converting this potential energy into work and kinetic energy.

It should be clarified that the total energy is always the same.

Consequently, on the top of the hill there is energy gravitational potential.
