A ball is released from Point X and rolls down a curved track. At which point will the ball have the GREATEST amount of kinetic energy?

A At the highest point of the track

B Just before it stops at the end

C At the lowest point of the track

D Halfway down the track

Worked Solution

Step 1: Gravitational potential energy (GPE) is converted into kinetic energy (KE) as the ball rolls down. Step 2: At the lowest point, the most GPE has been converted into KE (ignoring heat/sound loss). Step 3: Therefore, KE is highest at the lowest point.

Correct answer: At the lowest point of the track
