Reword this please (NOT to long, please.)
At max height of swing, potential energy is greatest, kinetic energy is least. At the bottom of the arc, potential energy is least, and kinetic energy is max
At the highest point of the swing, potential energy is at its peak, while kinetic energy is at its lowest. At the lowest point of the swing, potential energy is at its lowest, and kinetic energy is at its peak.
This as well, please. (not too wordy again)
The 16 pound shot will have more kinetic energy that the 12 pound shot. This is because the 16 pound shot is heavier than the 12 pound shot. Even though the 12 pound shot went farther, that doesn't mean it has more kinetic energy.
