Impulse
Impulse is the change in momentum of an object when a force is applied to it for a certain amount of time.
In short:
Impulse is the change in momentum.
Impulse equation
The equation for impulse is:
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 )
