Question

1. what is newtons first law of motion commonly called? the law of unbalanced forces the law of inertia the law of gravity the law of action - reaction

Explanation:

Newton's first law of motion 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 commonly known as the law of inertia.

Answer:

the law of inertia
