Question

3.
Give reasons for the following statements.. In a roller coaster, the potential and kinetic energy keeps on changing.​

Answer 1

Answer .) potential energy changes in a role coster because the track of the coaster ride is irregular ( up and down ) and we know that potential energy depend upon its mass and the height it is raised to . The up and down down movement of the roller coaster does not keep its potential energy constant .



Kinetic energy of a roller coaster does not remains constant because if we observe as we go up in the coaster track the speed of the roller gets slow and it stops and slowly slowly tilts and then moves very fast. As we know kinetic energy of a body depends upon its mass and the speed with which it moves . This non uniform motion of the roller does not keep the kinetic energy constant
