Question

what is inertia? what is Newton's first law.​

Answer 1

Answer:

SOLUTION

Newton's First law states that, "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force". 

This means that bodies does not change it's position on it's own.

The tendency to be in original state of rest or of uniform motion is inertia.

So, Newton's first law actually gives concept of inertia.

Answer 2

Answer:

• Explanation: Newtons first law say that,

 . net force will be zero

 .particle remains un accelarated

Inertia means,  . a body at rest tries to remain the same

                           . a body moving with uniform velocity tries to do so
