Question

state laws of inertia. how can u derive this law from second law of motion

Answer 1

We know that as per Newton's first law of motion, each object resists a change in its state of rest or of uniform linear motion. In a qualitative way, the tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called Inertia. Due to this very reason, the first law of motion is also known as the Law of Inertia.
Thus,Inertia of an object is inherent property by virtue of which it cannot change by itself its state of rest or of uniform motion along a straight line.


Hope this answer will clear all your doubts
Thankyou!

Answer 2

Explanation:

Newton's first law states that a body stays at rest if it is at rest and moves with a constant velocity unit if a net force is applied on it. Newton's second law states that the net force applied on the body is equal to the rate of change in its momentum.

F = ma

or F = m(v-u) / t

or Ft = mv - mu

That is, when F = 0, v = u for whatever time, t is taken. This means that the object will continue moving with uniform velocity, u throughout the time, t. If u is zero than v will also be zero, i.e., object will remain at rest.
