Linear Momentum

A vector quantity equal to the product of an object's mass and its velocity.

p = momentum [kgms-1]
m = mass [kg]
v = velocity [ms-1]

Increasing the speed of an object increases its momentum, and a heavy object will have more momentum than a lighter one moving at the same speed.

1 lb ft s-1=0.138255 kg m s-1

For an object moving at close to the speed of light this definition gets modified.

The total momentum is a conserved quantity in any process.
