Question

What is the first law of motion?

Answer 1

The focus of Lesson 1 is Newton's first law of motion- sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays inmotion with the same speed and in the same direction unless acted upon by an unbalanced force.

Answer 2

A body continues to stay in its state of rest or of uniform motion until and unless an external force acts on it..
