KIDS TRIVIA

Detailed explanation-1: -As the skateboarder goes down the ramp, potential energy is converted to kinetic energy. Because of friction, some of the energy in the system is converted to heat energy.

Detailed explanation-2: -The skateboarder is converting potential energy to kinetic energy as he goes down the hill. When you stretch a rubber band, you add potential energy to it by changing its shape.

Detailed explanation-3: -If starting from rest, the mechanical energy of the skier is entirely in the form of potential energy. As the skier begins the descent down the hill, potential energy is lost and kinetic energy (i.e., energy of motion) is gained.

Detailed explanation-4: -An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion).
