# Is the impulse a force?

Mar 27, 2018

An impulse is related to force. It is equal to $F \cdot t$, a force multiplied by the length of time the force was applied.

#### Explanation:

Impulse is also equal to change in momentum caused by the impulse. So you can say that

$\text{force" xx "the time the force was applied} = m \cdot \left(v - u\right)$

So if you know the change in momentum and time of contact, you can calculate the average force applied.

I hope this helps.
