Explain the transformation that takes place when you turn on a flashlight. From the battery to the light.
What is Chemical (of the battery) to electrical (flow of electrons) to radiant (of the light) to thermal ( the heat produced by the light)
100
As the speed of a falling object increases, its potential energy will
what is decrease
100
Type of energy that depends on the flow of electrons
What is Electrical Energy
100
What kind of energy is in a stretched rubber band?
Potential

Explain the transformation that takes place when you rub your hands together. START FROM THE SUN (5 steps)
What is light energy( from the sun) to chemical energy (plants make sugar) to chemical (stored in food) to mechanical (movement of the hands) to thermal (heat produced from friction)
200
Energy of Motion
What is Kinetic Energy
200
Type of energy that depends on the speed of the object.
What is Kinetic Energy
200
Where would this tossed baseball have the least amount of kinetic energy?
X

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.

As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy?
The potential energy decreases while the kinetic energy increases
