what is power
power is a measure of how quickly work is being done and how quickly energy is transfered

what is momentum
A moving object has momentum. This is the tendency of the object to keep moving in the same direction. It is difficult to change the direction of movement of an object with a lot of momentum.

how to you conserve momentum
As long as no external forces are acting on the objects involved, the total momentum stays the same in explosions and collisions. We say that momentum is conserved. You can use this idea to work out the mass, velocity or momentum of an object in an e

what are seatbelts
they stop you from moving around inside a car, and from hitting the windscreen and seatbelt, they stretch in a collision, they increase time taken for the bodys momentum to reach zero, so reduces the force on it
