The Difference Between Kinetic and Potential Energy

Kinetic Energy Defined00:00:06

Kinetic energy is the energy a body possesses due to its motion. Examples include a ball thrown upwards, a car traveling, a plane flying, and a person walking or running. The faster an object moves, the greater its kinetic energy. When an object stops, its kinetic energy becomes zero.

Potential Energy Defined00:00:59

If a ball is raised to a certain height and released, it starts falling, gaining kinetic energy. This kinetic energy comes from stored energy in the ball called potential energy. Potential energy is energy stored in a body due to its position, specifically its height from the ground. The higher the ball, the larger its potential energy, which converts to kinetic energy upon release.

Slingshot Example00:01:56

A slingshot stores potential energy based on the bird's position. When released, the bird gains kinetic energy, allowing it to apply force and break objects.

Exercise: Identifying Greatest Potential Energy00:02:20

In an exercise, the character 'Bubbles' has the most potential energy because she is at the highest position. Potential energy increases with a body's distance from the ground.

Summary of Key Differences00:02:40

In summary, potential energy is the energy of a body due to its position, primarily depending on its distance from the ground. Kinetic energy is the energy of a body due to its motion and depends on its speed.
