Question 7

A skier starts from rest at the top of a hill (point A). They slide down the slope without using poles, gaining speed, and then use their skis to brake to a complete stop at the bottom of the slope (point B).

Which sequence correctly describes the primary energy transfers that have taken place between A and B?

A

gravitational potential energy →\rightarrow→ kinetic energy →\rightarrow→ internal (thermal) energy

B

gravitational potential energy →\rightarrow→ internal (thermal) energy →\rightarrow→ kinetic energy

C

kinetic energy →\rightarrow→ gravitational potential energy →\rightarrow→ internal (thermal) energy

D

kinetic energy →\rightarrow→ internal (thermal) energy →\rightarrow→ gravitational potential energy
