The SI unit of linear momentum is:
Akilogram metre per second
Bnewton per second
Cnewton second squared
Dkilogram per second
Answer & Solution
Correct answer: A. kilogram metre per second
1. Linear momentum is defined as the product of mass and velocity (p = m·v).
2. Mass has the SI unit kilogram and velocity has m per second.
3. Multiplying them gives kilogram metre per second.
4. So the SI unit of momentum is kilogram metre per second.
