EnergyTypes & Forms

Page 2: Energy Types & Forms. What is Energy? The ability to do work

What is Energy?• The ability to do work

Page 3: Energy Types & Forms. What is Energy? The ability to do work

Types of Energy

Page 4: Energy Types & Forms. What is Energy? The ability to do work

Potential vs. Kinetic• Potential Energy

– Stored energy

• Kinetic Energy– Energy of motion

Page 5: Energy Types & Forms. What is Energy? The ability to do work

Forms of Energy

Page 6: Energy Types & Forms. What is Energy? The ability to do work

Mechanical Energy• The total energy of motion and position of an

object– Mechanical energy = potential + kinetic– Examples: rollercoaster, juggling

Page 7: Energy Types & Forms. What is Energy? The ability to do work

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

Page 8: Energy Types & Forms. What is Energy? The ability to do work

Chemical Energy• Energy stored in the bonds of atoms &

molecules– Examples: baking soda, fossil fuels

Page 9: Energy Types & Forms. What is Energy? The ability to do work

Electrical Energy• Energy of moving electrons

– Electrons are negatively charged particles– Examples: appliances

Page 10: Energy Types & Forms. What is Energy? The ability to do work

Sound/Acoustic Energy• Energy caused by the vibrations of an object

– Examples: guitar, speakers

Page 11: Energy Types & Forms. What is Energy? The ability to do work

Light/Radiant Energy• Energy produced by the vibrations of

electrically charged particles– Examples: sun, microwave, radio waves

Page 12: Energy Types & Forms. What is Energy? The ability to do work

Nuclear Energy• Energy that comes from changes in the

nucleus of an atom– Examples: sun, uranium, hydrogen

Page 13: Energy Types & Forms. What is Energy? The ability to do work

Magnetic Energy• Energy from the attraction of objects made of

iron– Examples: magnets, generators
