All moving objects have momentum. Forces can cause changes in momentum. The total momentum in a collision or explosion is conserved and stays the same. Car safety features absorb energy involved in a crash they slow down the collision thus reducing the force of impact.
Demo
In this tutorial you will learn how to calculate the momentum in a moving object.
The equation is written like this:
$P = { \text m\; \text x \; \text v}$
Chilled practice question
Calculate the momentum of a 1200 Kg vehicle travelling at 5 m/s.
Frozen practice question
A girl has a mass of 60 Kg. How fast is she moving if her momentum is 240 Kgm/s ?
Science in context
All moving objects have momentum. Forces can cause changes in momentum. The total momentum in a collision or explosion is conserved and stays the same. Car safety features absorb energy involved in a crash they slow down the collision thus reducing the force of impact.
