What is Potential ( due to the position of the book) to kinetic ( motion of the book) to thermal ( the friciton between the book and the air)
300
When you drop a book on the floor, what happens to its original potential energy?
What is the potential energy was transfered to kinetic and thermal energy

400
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
What is 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 conected to a generator that make a flow of electrons)
400
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.
400
Type of bond between sulfur and lithium?
What is ionic
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
500
Explain the transformation that takes place to make a toaster work using a wind turbine. Begin with the sun. (6 steps)
What is 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)
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.
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.
