Question

a) What is Inertia ? State Newton's first law of motion.​

Answer 1

Answer:

The First Law states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." This simply means that things cannot start, stop or change direction all by themselves.

Answer 2

Intertia:

The inherent property of a body to resist any change in its state of rest or the state of uniform motion unless it is acted upon by an external unbalanced force.

Newton's first law of motion

Every body continues to be in its state of rest or the state of uniform motion unless it is influnced by an unbalanced external force.

Hope this will be helpful.
