1/2mv^2
1/2x12x10^2=600J
The kinetic energy is 600J
Kinetic energy is the energy for a catapult.
T<span>he phenomenon of </span>static electricity<span> requires a separation of </span>positive<span> and </span>negative<span> charges. When two materials are in contact, electrons may move from one material to the other, which leaves an excess of </span>positive<span>charge on one material, and an equal </span>negative<span> charge on the other.</span>
A proton has a positive (1+) charge
