Tutorial

Momentum is the quantity of motion an object has.  Momentum depends on the mass and velocity of an object. The momentum of an object is in the same direction as its velocity.

To calculate the momentum of an object, the relationship between the object's mass (commonly measured in kilograms) and velocity (commonly measured in meters per second) can be used.  Measurements of velocity use the units kg*m/s.

Momentum = Mass (kg) * Velocity (m/s)

Example:

If a train has a mass of 20,000,000 kg, and is traveling at a velocity of 30 m/s, what is the train's momentum?

Mass = 20,000,000kg

Velocity = 30 m/s

Momentum = Mass (kg) * Velocity (m/s)

Momentum = 20,000,000kg * 30 m/s

Momentum = 600,000,000 kg*m/s
