What is impulse? Impulse is a term that quantifies the overall effect of a force acting over time. It is conventionally given the symbol J and expressed in Newton-seconds. For a constant force, J = F ⋅ Δ t . As we saw earlier, this is exactly equivalent to a change in momentum Δ p . This equivalence is known as the impulse-momentum theorem.
