Question

What is Impulse of Force?State its formula and SI unit.

Answer 1

Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time. So, with impulse, you can calculate the change in momentum, or you can use impulse to calculate the average impact force of a collision.

How do we calculate impulse:

An impulse is equal to the net force on the object times the time period over which this force is applied. Below, we derive impulse from the equation F = ma, which comes from Newton's second law of motion.

SI Unit of impulse:

The SI unit of impulse is the newton second.
