3.  1. Energy is the ability to do work or cause change.  2. You measure energy in joules.  3. 2 main type of energy is kinetic and potential.  4. Mass and velocity  5. Kinetic energy is the energy an object has due to its motion.  6. Potential energy is stored energy as a result of an object’s position or shape.

4.  7. Gravitational potential energy is the potential energy an object has due to its height.  8. Elastic potential energy is the potential energy an object gains when it is stretched or compressed. Examples: rubber band and a bow and arrow

5.  1. transferred or converted  2. Mechanical: energy associated with the motion of an object.  Thermal: the total energy of the particles in a substance or material  Chemical is the potential energy stored in the chemical bonds of an object  Electrical: is the moving electrical charges that produce electricity and energy  Electromagnetic: energy that moves in waves  Nuclear: energy stored in the nucleus of an atom, released during fission or fusion

6.  1. a change from one form of energy to another.  2. work gets done  3.Single transformation- is when energy changes from one type of energy to another  Multiple transformation- is when energy goes through a series of transformations.  4. Single: electrical thermal(toaster)  Multiple: M C T EM (This is process of striking a match.)

7.  5. potential to kinetic  6. created, destroyed, changes forms  7. Albert Einstein  8. a huge amount of energy

8.  Conduction: the transfer of heat from one particle to another by direct contact  Convection: the transfer of heat as it moves in currents  Radiation: the transfer of heat as it moves in EM waves  Insulator: stops or resist the flow of heat  Conductor: allows heat to flow through it easily
