Newtons first law states that an object will remain still or in straight line. Until acted upon some force!
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. Basically a object won't move (remain in rest) or will keep moving in a straight line unless acted on by a outside or force. For example if i had a water bottle on top of my desk the water bottle won't till i touch it or wind knocks it over.
