Physics-The Physics of Stopping

The question “safety is not related to how fast you go but how fast you stop” can not be answered without looking at the physics concepts involved. The answerer is not as clear cut as it may seem as factors of momentum, that is inertia in motion, inertia, mass, change in momentum, and impulse, all must be taken into account.
The first concept we must look at momentum. Momentum is inertia in motion, which can be found by multiplying mass and velocity. If you increase either mass or velocity, you will increase the momentum, we need to look at this as the faster you go the more momentum you have, and therefore the more dangerous you are, so speed is a danger, which is by no means a safe act.
The second important concept is the concept of impulse. Impulse changes momentum. Finding impulse is attained by multiplying force and time interval, change either of the two and the impulse is different. If you decelerate quickly you will have a smaller impulse, than a longer smoother...
