solar
300
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 sound ( the friciton between the book and the floor)
300
When you drop a book on the floor, what happens to its original potential energy?
The potential energy was transferred to kinetic and thermal energy and sound energy.
300
This type of energy is heat energy from the Earth's interior.
geothermal energy
300

A turbine (generator)
400
What is type of energy that depends on the flow of electrons
electrical energy
400
The type of energy transfer that occurs when hot water flows through cold water
convection
400

radiation
400
What is nuclear energy?
nuclear energy is energy stored in the nucleus of an atom.
400
The law used to describe why total amount of matter remains constant in a chemical reaction
The Law of Conservation of Mass
500

Chemical energy
500
When you burn your hand on the handle of a hot pot, the heat is transferred to your skin by...
conduction
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 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
The law of conservation of Energy suggests that...
Energy is only released, stored, or transformed. Energy is never created or destroyed.
