The ball in position E has only kinetic energy, no potential energy. (TRUE or FALSE)
FALSE The ball in position E has some potential and some kinetic energy.
A kid is jumping up and down on a pogo stick. When (or where) is all of his energy converted into almost all kinetic energy?
at the bottom of each jump (or just before touching the ground)
The image shows a stretched rubber band which is not yet moving. This is an example of ___________ energy.
potential
In the image, how does the potential energy of the woman half-way up the ladder compare to the potential energy of the woman on top of the ladder?
The woman half-way up the ladder has only half as much PE. (Or the woman at the top has twice as much as the woman half-way down the ladder.)
A skier going down a hill is an example of ____________ energy.
kinetic
At which position on this roller coaster image are potential and kinetic energy about equal?
Either position 2 OR position are correct answers.
Describe what happens to the potential and kinetic energy of the blue skateboarder as he goes from the top of the half-pipe to the bottom.
Potential energy changes into kinetic. (Or potential energy decreases, and kinetic energy increases.)
On a motocross race track, there can be many hills. When you are at the top of each hill you have less _____________ energy.
kinetic
Gas in a car tank, a battery, and food sitting on a plate are examples of ___________ energy.
chemical / potential
A boulder rolling down a hill is an great example of ___________ energy.
kinetic
In the bar graph shown in the image, potential energy + kinetic energy = __________ energy.
total
For the image, which is true?
Rolling the rock to the top creates more potential energy
how you get the rock there doesn't change PE
carrying it to the top creates more PE
lifting it with a crane would create more PE
An arrow in motion is an example of ___________ energy.
kinetic
As the dirt rally race car shown climbs the hill, how is potential energy changing?
potential energy is increasing
Which food item in the picture has more potential energy, the banana (yellow) or the eggplant (purple)?
the banana
What will happen to this water skier's potential energy as he falls back down toward the water?
potential energy will decrease
