• 1. What is Energy?
• 2. Energy is the ability to do workWork is done when a force moves anobject over a distance in thedirection of the force W = F x d (Force x Distance)Measured in Joules (j)
• 3. Potential EnergyKinetic Energy
• 4. The Energy of Position; The energy an object has because ofits position. The ability to haveenergy or stored energyExamples: The wound spring in a wind-up toy The stretched bow of a bow andarrow
• 5. Energy of Motion◦ All moving objects even protons,neutrons and electrons have it.◦ The greater the mass of the movingobject, the greater the Kinetic EnergyExamples:◦ The swinging of a hammer.◦ A ball rolling down a hill
