  • Elastic energy
• Energy -Is the ability to do work
• Kinetic Energy -The energy in moving matter and wave
• Potential Energy -the energy in matter due to the arrangements of its parts, its composition, location and structure; commonly considered as a stored energy having the potential to do mechanical work
• Energy Transformations - It is the change of one form of energy to another
• Energy transformation in a lamp:

  Electrical Energy to Light and Heat Energy.
• Energy transformation in a plugged tv:
