‘P’ of a body is defined as product of mass and velocity. What is P here?

Correct option is C

Correct Answer: (c) Momentum (vector quantity)
Explanation:
· The quantity P = mass × velocity (m × v) defines momentum, a vector quantity.
· Because velocity has a direction, momentum also has direction and follows vector addition laws.
Information Booster:
· Formula: p=m×v
· SI Unit: kg·m/s
· Momentum Conservation Law: In any isolated system, total momentum remains constant during collisions.
· Types of momentum:
· Linear momentum → p=mv
· Angular momentum → L=Iω
· Momentum is fundamental in mechanics for analyzing:
· Elastic & inelastic collisions
· Impulse-momentum theorem → FΔt=Δp
Additional Knowledge:
· Pressure (a & d):
· Defined as Force/Area (F/A)
· A scalar quantity, not derived from mass × velocity
· Units: Pascal (Pa)
