What is energy?
Energy
– the capacity to do work or to
accomplish a task
Energy Transformation
- the change of energy from one
form to another

Examples of Energy Transformation
Machines!
• Car
–From: fuel (chemical)
–To: motion (kinetic), heat (thermal),
noise (sound)
• Generator
–From: fuel (chemical) or falling water
(gravitational potential/kinetic)
–To: electricity (electrical)
