Potential vs. Kinetic Energy Notes TEKS 6.8A compare and contrast potential and kinetic energy

Energy is the ability to do work or cause change.

Law of Conservation of Energy states that energy cannot be created or destroyed.

Two types of energy…

Potential energy is energy that is stored, waiting to be released… it has the potential to do work.

Gravitational potential energy depends on an object’s position or height. more potential energy less potential energy

Chemical energy is stored in the chemical bonds of the compounds that hold substances together.

Kinetic energy is the energy of motion…

may be found in many forms such as… mechanical radiant (light) sound electrical thermal

Energy can be transformed or changed from one type to another.

Potential energy can be transformed into kinetic energy. potential energy kinetic energy

As an object’s kinetic energy increases the potential energy decreases.

Application: Decide if each the following pictures are potential or Kinetic energy

Battery

Running

Bicycle sitting
