Description

Conservation of Linear Momentum: Conservation of linear momentum is based on Newton’s second law of motion, which states that in an isolated system, the total momentum remains the same.

Let’s consider a case where a football of mass M2 is resting on the ground, and a bowling ball with a comparatively heavier mass of M1 is thrown at the football at a velocity of U1. When the bowling ball hits the football, the energy is transferred, and the bowling ball loses some velocity and moves at a new velocity V1 the football moves at velocity V2.

To conserve linear momentum, i.e. the bowling ball had an initial momentum of M1 so as M2 < M1 and the momentum of football should be equal to the momentum lost by the bowling ball.

According to the law of conservation of momentum, the football had no other option than moving at a velocity of V2.

The formula of momentum: Mathematically, it is given by,
M1u1 + M2u2 = M1v1 + M2v2

Note: M1u1 ≠ M1v1

Where M1 is the mass of the bowling ball, M2 is the mass of the football, u1 , and u2 are the initial velocities, and v1 and v2 are the final velocities.

Momentum is always conserved in any collision, whether it be an elastic or a non-elastic collision; though kinetic energy is not conserved in a non-elastic collision, the kinetic energy is converted into heat energy or potential energy, etc.
