Q
What objects have momentum?
A
- all moving objects have momentum
- if an object is not moving it has no momentum / its momentum is 0
4
Q
Why are safety features useful?
A
safety features such as: air bags, seat belts, gymnasium crash mats, cycle helmets and cushioned surfaces for playgrounds are important as the they increase the impact time the more the impact force is reduced which means the change in momentum occurs over a longer period of time
