What is Energy?
• Energy is the ability to do work.
• There are two main types of energy:• Potential• Kinetic
Potential Energy
• Energy that is stored and being held, waiting to be used is potential energy.
• Examples:• A car parked in a parking lot• A child at the top of a slide• A ball sitting on a table• Someone pulling a arrow back on a bow
Kinetic Energy• The energy of motion is kinetic
energy.
• Examples:• Rolling a ball down a hill• Going down a hill on a roller coaster• Riding your bicycle
What is Mechanical
Energy?
o Energy due to a object’s motion (kinetic) or position (potential).
The gears in a watch have mechanical
energy.
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.
