what is momentum? give a relevant real world example.
Asked by bhavyankajain20 | 4th May, 2018, 03:35: PM
Momentum is nothing but mass in motion. It is basically a product of mass and velocity.
Momentum (p)= mass (m)× velocity (v)
For example :
If ball of mass 2 kg is thrown and has velocity 10 m/s, then its momentum is
p=m x v= 20 kg.m/s
But momentum is a vector quantity. Hence its direction along with its magnitude has to be taken into consideration.
