Study Notes

Impulse in Classical Mechanics

Impulse is the change in momentum of an object.
The SI unit of impulse is Newton-seconds (Ns).

Relationship Between Impulse and Force

According to Newton's second law of motion, the impulse equals the force multiplied by the time over which it is applied.

Dimensionally Equivalent Unit of Momentum

The dimensionally equivalent unit of momentum is kilogram-meters per second (kg·m/s).

Calculating Impulse of a Varying Force

The impulse delivered by a varying force is calculated as the integral of the force with respect to time.
