... and faster speed, it gains more energy and must be met with a larger force to bring it to rest. Not surprisingly, the momentum can be calculated by multiplying the mass of the object times its velocity (p = m v). Therefore a car moving at 70 mph will have less momentum than a truck moving at the sam ...
