Energy Energy is the ability to do work or cause change. When a living thing does work on another object, some of that energy is transferred. Examples?
Kinetic Energy 1Kinetic energy is the energy an object has due toits motion; this depends on both it’s mass andit’s speed. More mass means more kinetic energy More speed means more kinetic energy Examples?
Kinetic Energy 2 Calculating Kinetic Energy:Kinetic Energy = 1/2 x Mass x Speed2Note- changing the speed has a greater impact on the object’s kinetic energy than changing the mass.
Potential Energy 1 Potential Energy is stored energy that results from an objects position or shape. This object has the potential to do work. When the object was placed where it is or shaped a certain way, energy was transferred to it. Examples?
Potential Energy 2Gravitational Potential Energy is an objects potentialenergy based on gravity. This is dependant on itsheight relative to a reference point and it’s weight.Elastic Potential energy is the potential energy of anobject that can be stretched or compressed
Law of Conservation of Energy According to the law of conservation of energy, energy cannot be created or destroyed. (sound familiar? What is another law that is similar to this?)
