Energy transformation in a rollercoaster​

Answer 1

Energy transformation in a Roller coaster

When the roller coaster car is at the top of the coaster, i.e., at point A, it possesses maximum potential energy. When it comes into motion and starts coming down, the height decreases and therefore the potential energy decreases but the kinetic energy increases.

When the roller coaster reaches the bottom of the ride, i.e., at point B, the potential energy becomes zero (as height=0) and the kinetic energy is maximum. This process goes on as the car moves from point B to C and so on.

At in-between points, the kinetic and potential energies continue to interchange. During the entire

path, the total mechanical energy (sum of the potential and kinetic energy) remains conserved. However, some loss of energy is witnessed due to friction.

The movement of a roller coaster is accomplished by the conversion of potential energy to kinetic energy. The roller coaster cars gain potential energy as they are pulled to the top of the first hill. As the cars descend the potential energy is converted to kinetic energy.
