Question

state the conservation of linear and angular momentum

Answer 1

A linear and angular momentum are different because a linear is straight

I hope this helps and have a nice day

Answer 2

Law of conservation of linear and angular momentum are the fundamental laws of nature.

As per the law conservation of linear momentum, the sum of momentum i.e the product of mass and velocity of an object or system of bodies will be always constant unless and until any external unbalanced force is acting.

Let us consider two bodies having masses m and m' which are moving with velocities u and u'. After sometime, two bodies undergo head on collision.

Let their final velocities are v and v'.

As per law of conservation of angular momentum-

              mu + m'u' = mv + m'v'

            i.e momentum p = constant.

Now, we have to define law of conservation of angular momentum.

Law of conservation of angular momentum states that the total angular moment of a system around any axis always remains constant as long there is no external unbalanced torque.

Let us consider a body of mass m which is moving with an angular velocity ω. Let I is the momentum of inertia of the body around any axis.

Hence, the angular momentum L = Iω.

As per law of conservation of angular momentum,

                                              L = Iω= constant       [ ∵net torque= 0]
