As the ball continues around the loop, its kinetic energy decreases while its potential energy increases. At the top of the loop, if the ball has sufficient kinetic energy, it can continue around the loop without leaving the track. If not, it falls away from the track as it approaches the top of the loop.

Potential energy is position relative. In other words, it changes depending on an object’s height or distance and the mass of the object. Kinetic energy changes depending on an object’s speed and its mass. At the top of the arc, the potential energy turns into kinetic energy as it swings back down.

On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. Traditionally, the coaster cars are pulled up the first hill by a chain; as the cars climb, they gain potential energy.

A roller coaster is fastest at the front of the train. The shorter the hill the roller coaster climbs, the greater its kinetic energy. Potential energy is converted to kinetic energy as the roller coaster goes down the hill. No conclusion can be made from this evidence.

When an object has the LEAST potential energy is when it has the MOST kinetic energy.

Kinetic energy is highest at point B and potential energy is lowest.

As an object falls under the influence of gravity, potential energy is less than kinetic energy after halfway point / before the halfway point.
