Question 75

A cyclist freewheels (coasts without pedaling) down a hill, starting from rest and traveling faster as they descend.

What best describes the change in energy stores?

A

gravitational potential energy→kinetic energy+internal energy\text{gravitational potential energy} \rightarrow \text{kinetic energy} + \text{internal energy}gravitational potential energy→kinetic energy+internal energy

B

chemical energy→kinetic energy+internal energy\text{chemical energy} \rightarrow \text{kinetic energy} + \text{internal energy}chemical energy→kinetic energy+internal energy

C

gravitational potential energy+kinetic energy→internal energy\text{gravitational potential energy} + \text{kinetic energy} \rightarrow \text{internal energy}gravitational potential energy+kinetic energy→internal energy

D

kinetic energy→internal energy+gravitational potential energy\text{kinetic energy} \rightarrow \text{internal energy} + \text{gravitational potential energy}kinetic energy→internal energy+gravitational potential energy
