Energy Changes
A. Energy—ability to cause change
B. Energy transformation—energy changes from one form to another without any
being lost or gained
C. Energy due to motion is kinetic energy.
1. An object’s kinetic energy depends on its speed and mass.
2. When objects collide, kinetic energy can be transferred.
D. Potential energy—stored energy due to an object’s position
E. Potential energy can be transformed to kinetic energy and kinetic energy can be
converted to potential energy.
F. Law of conservation of energy—energy cannot be created or destroyed; it can
only change form
1. Total amount of energy in the universe never changes.
2. Kinetic energy can be converted to heat energy.
