Forms of Energy
Objective: Can I recognize different types of
energy transformations?What is the Law of Conservation of
Energy?
Forms of Energy
MechanicalThermalChemical
ElectricalElectromagneticNuclear
Energy can be transferred, or
converted, from one form to
another!
Mechanical Energy
Energy associated with the motion of an object.
Rest + Motion
ChewingSoundFrog Dancing
Thermal Energy
Heat Energy
All objects give off thermal energy
Ice cream melting gains thermal energy
Chemical Energy
Potential energy stored in chemical bonds.

Law of Conservation of Energy
Energy can NOT be created or destroyed, only transformed from one form to another.
With every energy transformation some energy is always given off as heat energy.
