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.
