Explanation : When the lift falls, then the gravitational energy changed into the kinetic energy. Gravitational potential is associated with the mass of the lift and its position. When lift starts from rest , the mechanical energy of the lift change in the form of potential energy.
When the lift down than the potential energy lost and kinetic energy is gained. Lift loses height and gains speed.
The work is performed by the lift, when lift covers the distance against the gravitational force.
In order to understand how kinetic and potential energy works in an ski lift it is necessary to know its terms
Potential energy is the energy that a body located from its height above the ground has
Kinetic energy is the energy of a body that is in motion
for the ski lift:
Kinetic Energy: When the ski lift moves from floor to floor
Potential Energy: When the ski lift is standing on the floor and people enter.
Gravitational energy: the chairlift uses the force of gravity to lower and change from potential energy to kinetic energy, with its own weight
I hope its help you
