The ball on the rollercoaster exhibits different motions: gravitational potential energy conversion to kinetic energy during descents, uniform motion on flat sections, and deceleration when ascending. Each track segment corresponds to varying forces acting on the ball throughout its journey.
A rollercoaster track is made in the shape shown in Fig. 5.19. A ball starts from point A and escapes through point F. Identify the types of motion of the ball on the rollercoaster and corresponding portions of the track.

As the ball moves along the rollercoaster track, it demonstrates several types of motion. Initially, at point A, it experiences gravitational potential energy, converting to kinetic energy as it descends, resulting in accelerating motion. On flat sections, the ball exhibits uniform motion, maintaining a constant speed. As it ascends toward point F, the ball decelerates due to gravitational forces acting against its motion, reflecting a decrease in kinetic energy and an increase in potential energy. Each segment of the track corresponds to these changing motions, highlighting the principles of physics at play.
