Energy

________ is the ability to cause change.

lightbulb

A(n) ________ is a device that transforms electrical energy into light energy and thermal energy.

energy transformations

Some ________ are less obvious because they do not result in visible motion, sound, heat, or light.

Energy

________ can be stored and it can move from place to place.

Kinetic Energy

the energy a moving object has because of its motion

Joule

The SI unit of energy

Potential Energy

Stored energy due to position

Elastic Potential Energy

energy stored by something that can stretch or compress, such as a rubber band or spring

Chemical Potential Energy

Energy stored in chemical bonds

Gravitational Potential Energy

energy stored by objects due to their position above Earths surface

Mechanical Energy

the total amount of potential and kinetic energy in a system and can be expressed by this equation

The Law of Conservation of Energy

states that energy cannot be created or destroyed
