What is momentum? Don't spam❎❎
Answers
Explanation:
In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If m is an object's mass and v is its velocity, then the object's momentum is: \mathbf{p} = m \mathbf{v}.

Momentum :
● Defination :
Momentum of a body is defined as the product of mass of the body and the velocity of the body at a particular instant.
● Notation :
Momentum is denoted by "p"
● Formula
p = mv
Where p : momentum of the body
m : mass of the body
v : Velocity of the body
● Units
In SI system of units
Unit of mass : Kg
Unit of velocity : m/s
So unit of Momentum : kg m/s
In CGS system of units
Unit of mass : g
Unit of velocity : cm/s
So unit of Momentum : g cm/s
● Dimensions
[ p ] = [ m ][ v ]
[ p ] = [ M^1 ] [ L^1 T^-1 ]
[ p ] = [ L^1 M^1 T^-1 ]
