Impulse

Impulse is the change in momentum of an object when a force is applied to it for a certain amount of time.

Impulse is the change in momentum.

Impulse equation

The equation for impulse is:

\text{Impulse} = \text{Force} \times \text{time}

\text{Impulse} = F \times t

Where:

\text{Impulse} is the change in momentum of the object in kilogram meters per second (kgms^{-1})
F is the force applied to the object in newtons (N)
t is the time for which the force is applied in seconds (s)
