Type of energy that depends on the speed of molecules.
Thermal or heat energy

Explain the transformation of a book falling from table. Explain the type of energy and where it comes from. 3 steps
 Potential ( due to the position of the book) to kinetic ( motion of the book) to thermal ( the friction between the book and the air)
300
When you drop a book on the floor, what happens to its original potential energy?
Potential energy was transfered to kinetic and thermal energy
300
A transfer of thermal energy by the movement of particles from one part of a material to another. 
Convection
300
Transfer of thermal energy from one material to another by electromagnetic waves
Radiation
400
Type of energy that depends on the flow of electrons
Electrical energy

Explain the transformation of energy that occurs in a coal burning power plant. List the type of enrgy and where it comes from. 5 steps
Chemical (coal) to thermal (heat released from breaking the bonds of coal to boil water)to kinetic ( the steam makes) to kinetic (turbine move) to electrical (the turbine is connected to a generator that make a flow of electrons)

A basketball is dropped from a height of 2m and another identical basketball is dropped from a height of 4m. Which ball has more kinetic energy just before it hits the ground?
The basketball dropped from a height of 4m because it has more speed.
400

Explain the transformation that takes place to make a toaster work using a wind turbine. Begin with the sun. (6 steps)
Thermal energy (from the sun) to kinetic energy (of the wind) to kinetic energy (the blades to spinning) to electrical ( the turbine turns a generator and makes a flow of electrons) to thermal ( heat from the toaster) to radiant ( when the toaster get hot enough it will emit light)

When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how the law of conservation of energy is obeyed.
During each bounce, some of the kinetic energy of the ball in transferred into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.
500
Explain the law of conservation of energy in your own words.
Energy cannot be created nor destroyed. It can only be transferred.

What is the difference in a conductor and insulator?
Conductor is a material that thermal energy flows easily. Insulator is a material through which thermal energy does not flow easily.
