Copper wire is an example
What is a conductor?

What is potential or chemical?
200
2 most common form of energy
What is chemical or thermal?
300
energy related to the temperature of a substance
What is thermal or heat energy
300
Explain the transformation of a book falling from table. Use the types of energy not forms. 2 steps
What is an example of Potential ( due to the position of the book) to kinetic ( motion of the book)
300
When you drop a book, the original potential energy is transformed (3 forms)
What is the potential energy was transformed in to kinetic energy, thermal energy, and sound (mechanical)energy
300
A turning car wheel is an example
What is mechanical energy?
300
2 types of energy and give an example for each
What is potential and kinetic energy?
400
energy produced by electric charges
What is electrical energy
400
Explain the transformation of energy that occurs in a windmill. 3 steps
What is Chemical (Sun) to mechanical (moving blades)to electrical (electricity produced)
400
A basketball is dropped from a height of 2m and another identical basketball is dropped from a height of 4m. One ball has more potential energy.
What is The basketball with a height of 4m because its starting position is higher?
400
Food is an example
What is chemical energy?
400
State the Law of Conservation of Energy
What is Energy can not be created of destroyed it can only be transfered or transformed?
500
energy stored in matter because of its chemical composition
What is Chemical energy?
500
Explain the transformation that takes place to make a toaster work. (2 steps)
What is electrical (outlet) to thermal ( when the toaster get hot enough it will cook toast)
500
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 the 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.
What is During each bounce, some of the kinetic energy of the ball in transfered 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.

Boiling water is an example.
What is thermal energy?
