Energy Types & Forms
What is Energy? The ability to do work
Types of Energy
Potential vs. Kinetic Potential Energy Kinetic Energy Stored energy Energy of motion
Forms of Energy
Mechanical Energy The total energy of motion and position of an object Mechanical energy = potential + kinetic Examples: rollercoaster, juggling
Thermal Energy All of the kinetic energy due to random motion of particles that make up an object Depends on speed & number of particles Examples: boiling water, rubbing hands together
Chemical Energy Energy stored in the bonds of atoms & molecules Examples: baking soda, fossil fuels
Electrical Energy Energy of moving electrons Electrons are negatively charged particles Examples: appliances
Sound/Acoustic Energy Energy caused by the vibrations of an object Examples: guitar, speakers
Light/Radiant Energy Energy produced by the vibrations of electrically charged particles Examples: sun, microwave, radio waves
Nuclear Energy Energy that comes from changes in the nucleus of an atom Examples: sun, uranium, hydrogen
Magnetic Energy Energy from the attraction of objects made of iron Examples: magnets, generators
