Detailed explanation-1: -As the biker goes up the hill, kinetic energy decreases while potential energy increases. At the top of the hill, the biker has maximum potential energy but minimum kinetic energy. As the biker goes down the hill, kinetic energy increases while potential energy decreases.

Detailed explanation-2: -energy ready to go. A race car at the starting line of a race, a bicycle on top of a hill, and students waiting to go home from school are all examples of potential energy.

Detailed explanation-3: -Kinetic energy is the energy of movement; moving objects perform work by imparting movement to other matter. A coasting bicycle has kinetic energy since it is moving down the hill.

Detailed explanation-4: -Bicycling is a rich source of kinetic energy.

Detailed explanation-5: -At an object’s maximum height, kinetic energy is zero/maximum while the potential energy is zero maximum.
