Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will continue in the same direction and speed unless acted upon by an external force. Therefore, the object moving at 50 miles/hr will continue moving in the same way until it is acted upon by a force.
