Momentum:



Define:

Momentum is a value of an object's mass and motion of an object. An objects momentum is the product of it's mass and velocity. If an object has a mass of 50kg and is moving with a velocity of 50m/s north, it has a momentum of 2,500kg*m/s north. Momentum is a vector quantity, meaning it's described by magnitude and direction.

Units

(base or derived): kg = kilograms m = meters s = seconds kg * m/s

Explain:

A car has a mass of 40kg and a velocity of 0 ms/s. What is the car's momentum? The car's momentum is 0 because the product of the cars mass and velocity is 0.

A car has a mass of 40kg and a velocity of 30 m/s. What is the car's
momentum? The car's momentum is 1,200kg*m/s because the product of the car's mass and velocity is 1,200.

Examples:


Equations:

p = momentum
m = meters
v = velocity
P = MV
