ability to do work, which is to cause something to move
Unit for Energy
Joules (J)
Unit for Power
Watts (W)
Potential Energy
stored energy; energy of position or condition
Gravitational Potential Energy
related to the height above Earth's surface; greater the height therefore greater of this
Kinetic Energy
energy in motion; amount depends on mass of moving object and velocity at which it is moving
Law of Conservation of Energy
energy may change from one form to another, but the total amount of energy remains constant; it cannot be created nor destroyed but may change form
formula for potential energy
mass x acceleration due to gravity x height
formula for kinetic energy
mass x (velocity squared) divided by 2
energy transformation
A change from one form of energy to another
