Two Main Types,..• Turn to page D 122
• Kinetic Energy: The energy of motion. Any moving object has some kinetic energy
• Potential Energy: stored energy, or the energy an object has because of its position or shape

Nature of Energy
• What is energy that it can be involved in so many different activities?– Energy can be defined as the
ability to do work.– If an object or organism does
work (exerts a force over a distance to move an object) the object or organism uses energy.

When the ball strikes the pins, mechanical
energy is transferred to the pins!

energy that is transformed into
thermal energy when the match is struck.

What is Thermal Energy?
o Heat energy
o The heat energy of an object determines how active its atoms are.
A hot object is one whose atoms and molecules are excited and show rapid
movement.
A cooler object's molecules and atoms will show less
movement.

Electrical Energy at work• Batteries store chemical energy and
transfer it to components in an electrical circuit.
• This chemical energy is converted into electrical energy.
• Circuits have to have a complete loop for an electrical current to pass through.

Energy Transfer
• Energy can be changed from one form to another.
• Changes in the form of energy are called energy transfer.

transformed (changed), all of that energy still exists in
some form
