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

All moving objects have momentum.

The greater the mass and the greater its velocity, the more momentum it has.

Momentum is a vector quantity and has size and direction.

'Momentum before = momentum after' in a closed system = Conservation of momentum.

• Two skaters skate towards each other.
• Skater A is 80kg and is moving at 2m/s.
• Skater B is 60kg and is moving at 1.5m/s.
• Total momentum before collision = (80x2)+(60x-1.5)
• =70kg m/s
• Total momentum…
