Momentum depends upon__________________?
Correct answer: D. both mass and velocity of the body
- A. force acts on the body
- B. mass of the body
- C. velocity of the body
- D. both mass and velocity of the body
Explanation
Linear momentum is defined by p = mv, so it depends on both the mass m in kilograms and velocity v in metres per second, with momentum measured in kg m/s. Option d is correct; choosing only option b or c ignores one of the two factors in the formula.

About Linear Momentum
Linear momentum is the vector product of mass and velocity, p = mv, and changes when a net external force acts. Work includes impulse as the change in momentum, conservation of momentum in isolated systems, collisions and explosions, and the distinction between elastic, inelastic and perfectly inelastic collisions.
