## What is impulse write it’s formula?

Mathematically, impulse is represented as the product of the force acting on the object and the time for which it is acting. Therefore, it can be written as. J=F. Δt.

## What is impulse equal to?

Impulse ( F Δ t F \Delta t FΔt ) Product of the average force exerted on an object and the time interval during which the force is exerted. Impulse is equal to the change in momentum ( Δ p \Delta p Δp ) and is sometimes represented with the symbol J.
