ENERGY
What is it and what kinds are there?
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
Potential vs. Kinetic
• When one increases, the other decreases.
Potential vs. Kinetic
• When one increases, the other decreases.
Other Types of Energy…
• Mechanical
• Electromagnetic
• Electrical
• Chemical
• Thermal
• Sound
What is Mechanical
Energy?
o Energy due to a object’s motion (kinetic) or position (potential).
The gears in a watch have mechanical
energy.
Other examples of Mechanical Energy
What is Electrical Energy?
o Energy caused by the movement of
electrons
Examples of Electrical Energy
What is Chemical Energy?
o Energy that is available for release
from chemical reactions.
Examples of Chemical 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.
Examples of Thermal Energy
What is SoundEnergy?
Sound is the movement of energy through substances in
waves.
Examples of Sound Energy
What is Electromagnetic
Energy?
Includes energy from gamma rays, x-rays, ultraviolet rays,
visible light, infrared rays, microwave and radio bands
