Summary
Highlights
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.
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.
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.
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.
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.
