Momentum

Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a direction as well as a magnitude. The SI unit for momentum is kg m/s.

Introduction

Momentum is a fundamental concept in physics. It is conserved in a system unless acted upon by an external force. This principle is known as the law of conservation of momentum.

Mathematical Definition

Momentum (p) is mathematically defined as the product of the mass (m) and velocity (v) of an object. This can be represented as:

p = mv

Conservation of Momentum

The law of conservation of momentum states that the total momentum of a closed system is constant if no external forces are acting on it. This principle is widely used in the analysis of collisions and other interactions in physics.

Impulse and Momentum

Impulse is the change in momentum of an object when a force is applied over a period of time. It is equal to the product of the force and the time interval during which the force is applied. The relationship between impulse and momentum is given by the equation:

Impulse = Change in Momentum
