10 Examples of Kinetic energy Kinetic energy is the energy of MOTION. Potential energy Kinetic energy can cause change. The amount of Kinetic energy in an object depends on 2 things- its mass & speed. 10 Examples of Kinetic energy ball falling off a table cyclist going downhill Definition Characteristics Examples

10 Examples of Potential energy Potential energy is STORED energy that an object has. Kinetic energy Stored Potential energy can cause change, just like kinetic energy. Energy can be stored in or by gravity, springs, elastic, and even chemical bonds, and others. 10 Examples of Potential energy airplane high in the sky ball sitting on table Definition Characteristics Examples

Energy Mechanical energy Potential energy Kinetic energy ?

5 Examples of Mechanical energy Mechanical energy is the Kinetic energy PLUS the Potential energy. Potential energy Kinetic energy The object is moving, but there is still stored energy in it. 5 Examples of Mechanical energy a ball falling skater going downhill Definition Characteristics Examples
