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
State the Law of Conservation of Energy
What is Energy can not be created of destroyed it can only be transformed.
400
This is a type of energy that travels in waves and can travel through empty space.
What is light energy
500
Type of energy stored in bonds of molecules
What is Chemical Energy
500
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 mechanical ( the steam makes) to mechanical (turbine move) to electrical (the turbine is connected to a generator that make a flow of electrons)
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 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.
