momentum

Mass X Velocity, I belive, Mass X Velocity Squared being the formula for energy. So I understand, anyhow.

Momentum, of course, being the stuff that rolling stones really gather.

Kinetic energy = 0.5mv^2 or one half the mass times the velocity squared.

.5 mass - thanks for the correction

As has been said.

Momentum: p = mv
Kinetic eneregy: K - 1/2 mv ^2

Isn't this something you could have either looked up in your textbook, or googled?
