1. 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.

2. 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.

3. Energy Conversions Solar to electricity Plants convert energy of sun to chemical Electromagnetic to mechanical Chemical to electromagnetic Mechanical to electromagnetic
