Question

what does newtons first law of motion state? a: an object in motion will stay in motion unless acted upon by an external force. b: for every action, there is an equal and opposite reaction. c: force equals mass x acceleration.

Explanation:

Newton's first law of motion, also known as the law of inertia, states that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an external force. Option B describes Newton's third - law and option C describes Newton's second - law.

Answer:

A. An object in motion will stay in motion unless acted upon by an external force.
