Energy

• Energy is the capacity for doing work.
• Kinetic energy is the energy of motion.
• E=mvv/2 (energy is proportional to the mass of the object and the square of the velocity).
• The work done by a net force on an object is equal to the change in the kinetic energy of that object.
  
  
• Potential energy is the energy of an object due to its location.
• (A car at the top of a hill has more potential energy than one at the bottom.)
• E=mgh (where h is the height).
• Conservation of energy. Energy can't be created just converted from one form to another.
• We've not talked about chemical energy, heat, or strong or weak nuclear forces (and I don't think we will in this module).
