![]() ![]() Where m A = mass of object A, u A = initial velocity of A, and v A = final velocity of A It is called the law of conservation of momentum. Then, for an ideal collision, the sum of momenta of the two (or more) objects (before the collision) is equal to the sum of momenta of those objects after the collision, provided there is no external biased force acting on them. Let two objects of different masses moving with different velocities collide. The student running in a race represents a mass moving with velocity. A student running a race with some velocity has high momentum.Hence, it impacts a high momentum on the body. Although the size of a bullet is small, it acquires a high velocity.While watching a sport, you often comment that this sports team has a lot of momentum.As a result, the casualty rate increases. It is because the impact of momentum when a high-speed vehicle collides with another vehicle is far more than that of low speed. Road accidents at high speed are worse than at low speed. ![]() If you do not exercise regularly, the body will have negative momentum, which will be hard to remove! Like, I know exercise has great momentum on one’s fitness.
