Question

Define Inertia? which is known as frist law of motion?​

Answer 1

Answer:

Explanation:

Law of inertia, also called Newton's first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. ...

Answer 2

Inertia is a tendency of undisturbed objects to stay at rest or of uniform motion in a straight path.
The first law of inertia states that :
An object remains in the star of rest or of uniform motion unless it is compelled to change its state by an external imbalanced force.
