This weight lifter accidentally put 25kg on the LEFT side of his barbell and 50kg on the RIGHT side of his barbell. Which side would have the MOST gravitational potential energy?
His left side because it has less mass.
His right side because it has less mass.
His left side because it has more mass.
His right side because it has more mass.
The weight lifter evened out his weights. On his FIRST lift he lifted a total of 100kg. On his SECOND lift he lifted a total of 50kg. If he lifted them both to a height of 2 meters, which lift would hit the floor with the most energy when dropped from the 2 meter height?
The FIRST lift, because less mas means more energy transferred.
The FIRST lift because more mass means more energy transferred.
The SECOND lift because less mass means more energy transferred.
The SECOND lift because more mass means more energy transferred.
A skate boarder was going back and forth from the top of a half pipe, down to the bottom and back up to the top of the other side. At which point would he have the MOST kinetic energy?
At the top, when he began.
At the top, where he turned around.
Half-way down either side.
At the bottom of the half pipe.

Jenna walks up the hill while Robert runs up the hill. Once they both reach the top, which person has gained the MOST potential energy?
Jenna, because she used less energy getting up the hill.
Robert, because he used more energy getting up the hill.
Neither, because they both used kinetic energy to get up the hill.
Both, because they are the same distance from the bottom of the hill.
