#### 'The Physics of Stopping,' is an answer to whether or not the statement "safety is not related to how fast you travel, but how quickly you stop," is true.

There must be a change in momentum. This change in momentum is known as the impulse. Impulse is the force acting multiplied by the time it acts for. It can be represented by the formula ∆P = F x ... by the formula ∆P = F x t, where ∆P stands for the change in momentum, F stands for the force, and t stands for the time. Looking at this formula you can see that when if the change in mom ...
