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?
What is The basketball dropped from a height of 4m because it has more speed.

Explain hydroelectric energy and give one advantage and one disadvantage.
What is hydroelectric energy is using the potential energy of water and turning it into electrical energy. One advantage is it does not pollute. One disadvantage is that it disrupts aquatic life.
400
State the Law of Conservation of Energy
What is Energy can not be created of destroyed it can only be transfered or tranformed.
500
Type of energy stored in bonds
What is Chemical energy

Explain the transformation that takes place to make a toaster work using a wind turbine. Begin with the sun. (6 steps)
What is thermal energy (from the sun) to kinetic energy (of the wind) to kineitc energy (the baldes to spining) to electrical ( the turbine turns a generator and makes a flow of electons) to thermal ( heat from the toster) to radient ( when the toaster get hot enough it will emmit 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.
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.
500
Explain how nuclear energy is used to create electricity and give one advantage and one disadvantage.
What is Uranium atoms are split and heat is released to boil water. The boiling water creates steam. The steam turns a turbine and the turbine tunrs a generator, which makes a flow of electrons. One advantage is that is does not pollute the air. One disadvantage is that is makes radioactive waste.
