Paul O’Malley(24449318) Physics 118 Homework #1 Ways energy is transformed 1. A wrecking ball being dropped goes from gravitational potential energy into kinetic energy. 2. Lighting gasoline- When you light a grill all of the chemical energy in the gas gets turned into Thermal energy. 3. Burning an ant- light energy gets turned into thermal energy 4. Hammering a nail- Gravitational potential energy in the hammer and chemical energy in your muscles gets converted into kinetic energy. 5. Energy from the sun is converted into thermal energy and heats up blacktop.
