Forces and Motion

Momentum - Calculations.

If an object with a mass of 26kg travels with a velocity of 5 m/s,
what is its
momentum?

momentum = mass x velocity
    
= 26 x 5
             = 130 kgm/s.


What happens to the momentum if we double the mass
of an object?
An object with a mass of 52kg travels with a velocity of 5 m/s,
what is its
momentum?

momentum = mass x velocity
    
= 52 x 5
             = 260 kgm/s.

If we double the mass of an object we double its momentum.


What happens to the momentum if we double the velocity
of an object?
An object with a mass of 25kg travels with a velocity of 10 m/s,
what is its
momentum?

momentum = mass x velocity
    
= 26 x 10
             = 260 kgm/s.

If we double the velocity of an object we also double its momentum.

We say that momentum is directly proportional
to both mass and velocity.
