Question

Define linear momentum. Show that its SI unit is Ns

Answer 1

Linear Momentum is a vector quantity.It can be define as the product of mass and velocity. It is denoted by "p".
p=mv
It's SI unit is kg m/s^2

Answer 2

Mathematically, linear momentum is the product of mass and velocity of an object. It is a vector quantity with direction same as that of velocity and magnitude mv.

SI unit:
the unit is kg × (m/s) = kg m/s = (kg m/s²) × s = N s
So the unit can be written as Ns.
