What is the unit of measurement for impulse?

Impulse is defined as the change in momentum of an object when a force is applied over a period of time. Mathematically, impulse (J) can be expressed as:

J = F × Δt,

where F is the force applied and Δt is the time duration for which the force acts. The unit of force is the Newton (N), and the unit of time is seconds (s). Therefore, when you multiply force (Newtons) by time (seconds), the resulting unit for impulse is Newton-seconds (Ns).

This aligns with the definition of impulse as the overall effect of a force acting over time, leading to a change in momentum. Thus, impulse is properly measured in the unit Newton-seconds.
