Energy Conversions

• Changes in forms of energy (one form to another) are called energy conversions.

• One of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy.

• When objects fall, they lose their potential energy because its height decreases.

Energy Conversions

• When objects fall, potential energy is converted into kinetic energy and the kinetic energy increases due to the velocity increasing.

• Example of ball increasing in altitude p.116. (Kinetic to Potential)

• All forms of energy can be converted to other forms.
