Answer:
Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.
An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy.
Explanation:
Answer:
1. Planets; movement of planets around the sun and other stars in the galaxy is kinetic energy
2. Rubber Bands; can be classified as both potential and kinetic energy, depending on the state of the band (when stretch=potential energy; when released=kinetic energy)
3. Rivers; strictly kinetic energy. the water is constantly moving creating kinetic energy.
