This graph shows a bouncing ball over time. Check all that apply.
As the ball falls to the ground, the GE transforms into KE and Elastic Energy.
As the number of bounces increases, the GE also increases.
The graph shows that the ball's total energy decreases with each bounce.
There is the same amount of Elastic Energy present in each of the five bounces.
the ball will eventually stop because its energy will transfer to the air as sound and thermal energy.

X
Y
Z
There is less GE at Y than at W because...
W is at a lower elevation that Y.
W is at a higher elevation that Y.
They both have the same GE.
There is not enough information to answer the question.
Which of the following is true?
A battery transforms chemical energy into electrical energy.
The light bulb will turn on when the circuit is opened.
The electrical energy transforms to both light and thermal energy in the light bulb.
The battery's chemical energy is considered a type of kinetic energy.
Energy from the light bulb is transferred to the the surrounding air molecules in the form of thermal energy.
In 1908, a meteorite impact occurred in Russia. The black dot shows where it hit while the dashed line shows the area of damage. What might be some reasons for this? Check all that apply.
The meteorite had a large mass.
The meteorite was brown in color.
The meteorite gave off a bright light.
The meteorite was moving at a high speed.
The meteorite travelled a long distance in the solar system.
You and a friend make an old-fashioned telephone with string and cups. You talk into the cup and your friend can hear you. Explain why. Check all that apply.
The Kinetic Energy from their your vocal cords is transformed into chemical energy.
The Sound Energy from your vocal cords is transferred to the string through a vibration or back and forth motion.
The type of string and material used can affect how well you and your friend hear each other.
This example is not real. Sound Energy can't transfer through solids like a cup and string.
