Energy

  1. 1. ENERGY!!!!!!!!
  2. 2. 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?
  3. 3. 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?
  4. 4. 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.
  5. 5. 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?
  6. 6. 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
  7. 7. 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?)
