Momentum, Mass, and Velocity
The more momentum an object has, the harder it is to stop the object or change its direction. For example a Quarter horse and Clydesdale horse have the same velocity. The Clydesdale's mass and momentum are bigger then a quarter horse's mass and momentum. So, a larger force is needed to stop the Clydesdale Horse.
How to Calculate Momentum
The formula for momentum is P = M x V. M is the mass of the object in kilograms and V is the object's velocity in meters per second. The units of momentum are kilograms multiplied by meters per second, or kg m/s. Like velocity, momentum has a direction as well. Its direction is always the same as the direction of the object's velocity.
