Question

newtons first law is also known as the law of... motion inertia friction gravity

Explanation:

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 property of objects to resist changes in their state of motion is called inertia. So, Newton's First Law is also known as the law of inertia.

Answer:

Inertia
