Linear Momentum and Impulse

• Define the term Linear Momentum, SI units and Dimensions
• State the principle of conservation of linear momentum and derive an expression for it

Introduction

Linear momentum is defined as the product of mass and velocity and is denoted by P.

Mathematically,$$\text{P = mv}$$where ‘m’ is the mass of the body and ‘v’ is its velocity.
