Q: What is the unit of the physical quantity, Momentum?
  • A. Newton-second
  • B. Joule-second
  • C. Erg-second
  • D. Pascal-second
Correct Answer: Option A - The momentum of any body is the product of their mass and velocity and the applied force on the body is become equal to rate of change of his momentum. The symbol of momentum is 'p'. This is a vector quantity and its unit is kg.m/sec or Newton-second.
