<strong>Energy</strong> Fast Facts Fast Facts<br />
• <strong>Energy</strong> is the ability to do work.<br />
• Work involves movement.<br />
• Any object with energy that moves is working.<br />
• There are five types of energy: mechanical, heat, chemical, electromagnetic,<br />
<strong>and</strong> nuclear.<br />
• Einstein was one of the first scientists to work with energy.<br />
• E=mc 2 energy is equal to mass times the speed of light squared.<br />
• The law of conservation of energy states that energy can be changed<br />
from one form to another, but cannot be created or destroyed.<br />
• Joules are units of energy.<br />
• Newton-Meters are units of work.<br />
• 1 Joule is equal to the work done when the force of 1 Newton produces<br />
1 meter of displacement.<br />
• Two forms of mechanical energy are potential <strong>and</strong> kinetic.<br />
• <strong>Potential</strong> energy is stored energy.<br />
• <strong>Kinetic</strong> energy is energy in motion.<br />
• <strong>Potential</strong> energy is converted into kinetic energy when the object<br />
begins to move, or work.<br />
• Everything has potential energy stored in it.<br />
• KE=.5 x mass x velocity 2<br />
• Mass = object’s volume times density<br />
• Velocity = distance object travels/time<br />
• Velocity = distance (d) divided by time (t)<br />
• PE = m x g x h<br />
• PE = mass times gravity times height<br />
• A pendulum can illustrate the law of conservation.<br />
