Energy
•The ability to do work or cause
change. (Work – the movement of an
object through a distance).

The Law of Conservation of Energy
•In physics, the law of conservation
of energy states that the energy can
not be created or destroyed, only
transformed.

Kinetic Energy• Energy resulting from the motion of an object.
• The amount of kinetic energy an object has is
determined by the mass and speed (velocity) of the
object.

Potential Energy
•This is stored energy. An object has
potential energy because of its position
or composition.
•Ex: A bike on top of a hill.

Gravitational Potential Energy
•Energy an object possesses because of its
position in a gravitational field.

Energy Transformation
•Energy can be transformed
(changed) from one form to another.
•EX: Flipping a switch to turn on a light.

Speed
• A measurement of how fast an object moves relative to a
reference point.
• It does not have a direction.
• Example – The racecar was driving at 160mph around
the track.

Velocity
• The speed of an object in a certain direction.
• Example – The car was driving 160 mph northeast
around the track.

Mass
• A measure of how much matter is in an object.

Gravity
• A force which tries to pull two objects toward each other.
• Anything which has mass also has a gravitational pull. The more
massive an object is, the stronger its gravitational pull is.

Joule
• The basic unit of electrical energy, and is equal to the work completed when one ampere of current is passed through a resistance of one ohm for one second.
• An example of joule is what a scientist would use to measure energy.
