1. ENERGY

2. WORK is… a FORCE is… ENERGY is… when a FORCE moves an object
the ability to cause a change or do work
WORK is…
when a FORCE moves an object
a FORCE is…
a push or a pull

3. There are two main kinds of energy…
POTENTIAL ENERGY
KINETIC ENERGY
Stored energy due to the interaction between objects or particles
Energy in motion or energy that is being used
Examples:
Examples:

4. Identify Each of the following as either POTENTIAL or KINETIC energy.
zzzz K P K K P

5. Types of POTENTIAL ENERGY
Gravitational Potential Energy
energy of an object that has mass and height above Earth’s surface– the greater
the height or mass, the greater
the potential energy.
Elastic Energy
Associated with objects
that can be stretched
or compressed

6. CHEMICAL ENERGY
The energy stored in and released from the bonds between atoms. Energy found in chemical bonds of food, fuel, batteries, etc.
NUCLEAR ENERGY
The energy stored in and released from the nucleus of an atom. Released when atoms are split or joined together

7. The energy in an electric current created by the movement of electrons
Types of KINETIC ENERGY
MOTION KINETIC ENERGY
Energy due to the
movement of an object
ELECTRIC ENERGY
The energy in an electric current created by the movement of electrons

8. SOUND ENERGY
Energy carried by
sound waves
RADIANT ENERGY
Energy carried by electromagnetic waves – visible light, gamma rays, and x-rays

9. Combined Kinetic Energy and Potential Energy
MECHANICAL ENERGY
Energy to move another object through a combination of motion (kinetic) and position (potential)
THERMAL (HEAT) ENERGY
Energy of the vibrating
particles (kinetic) IN an object
and the attraction between
the particles (potential)
