momentum
mass x velocity - kgm/s
conservation of momentum
in an isolated system
the total momentum beforea collision = the total momentum after a collision
equation for force with cahnge in momentum
this shows that the force decreases with a increase in the time
therefore with same change of momentum we can reduce the force experienced
how does car safety utilise the equation for forece with change in momentum
rely on use of crumple zones - airbags, seatbelts
impulse
the change of momentum of an object when the object is acted upon by a force for an interval of time
force - time graphs
area under graph is the impulse
