Momentum

What is momentum?

Momentum is the movement of mass in motion and the tendency for it remain in motion; referring to the quantity of motion an object has. If an object remains at rest the momentum equates to zero despite its mass

What is the equation for momentum?

Momentum is the mass of the body multiplied by its velocity

Mass (kg) x Velocity (m/s) = momentum

What is the unit of momentum?

The units of momentum are the products of the units of mass (kg) and velocity (m/s), leaving the units in kilogram meters/second (kg m/s)

If an object is at rest, and has a mass of 2000 kg, what it its momentum?

Because the object is at rest (not moving) the momentum of it equates to zero despite the mass of the object

State the law of conservation of momentum

The law of conservation of momentum states that the total momentum of a closed system does not change.

This means that when two object collide, the total momentum before the collision equals the total momentum after the collision
