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
A spark plug in an automobile produces electrical energy to ________________ energy.
What is mechanical energy?
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 chemical 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 mechanical energy (the blades to spinning) to electrical ( the turbine turns a generator and makes a flow of electrons) to thermal ( heat from the toaster) to radient/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.
