Linear Momentum Formula

Linear momentum (p) is a vector quantity, which is the product of an object’s mass (m) and its velocity (v). Mathematically, it is represented as:

p = m × v

Where,

  • p = linear momentum
  • m = mass of the object
  • v = velocity of the object.

Linear Momentum – Definition, Formula, Examples

Linear Momentum is the physical property of a mass moving with a certain velocity in a straight line path. Linear momentum is given as the product of the mass of the object and the velocity with which it is moving. In the physical world, we can realize the significance of linear momentum from the fact that a heavier body with a higher velocity creates more destruction than a smaller body with the same velocity.

In this article, we will understand the meaning of linear momentum, the formula of linear momentum, linear momentum of a system of particles, and the law of conversion of linear momentum.

What is Linear Momentum?

Linear momentum is a fundamental concept in physics that describes the motion of an object in a straight line. It is a vector quantity defined as the product of an object’s mass and its velocity. It means a body with a larger mass and a faster speed has more momentum than one with a smaller mass and a slower speed. We can understand the importance of momentum with the fact that the object with more momentum will cause more destruction than the one with smaller momentum....

Linear Momentum of a System of Particles

Linear momentum of a system of particles arises from interactions among the particles, leading to the principle of conservation of linear momentum (P). This principle states that the total linear momentum of the system, equal to the sum of the linear momenta of every individual particle, remains constant. If a system comprises n particles, the total linear momentum is given by the sum of the linear momenta of each particle....

Law of Conservation of Linear Momentum

The law conservation of linear momentum is a fundamental law in physics that states that the total linear momentum of a closed system remains constant if no external forces act upon it. In other words, for a closed system, total momentum before an event, such as a collision or explosion is equal to the total momentum after the occurrence of the event. Mathematically, this principle can be expressed as:...
