according to newtons first law of motion, when will an object at rest begin to move? when its inertia decreases to zero when an unbalanced force acts upon it when the action and reaction forces are equal when two equal and opposite forces act upon it

according to newtons first law of motion, when will an object at rest begin to move? when its inertia decreases to zero when an unbalanced force acts upon it when the action and reaction forces are equal when two equal and opposite forces act upon it

Answer

Brief Explanations:

Newton's first - law states 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. Inertia is a property of matter and cannot decrease to zero for a non - zero mass object. Equal action and reaction forces act on different objects. Two equal and opposite forces acting on an object result in a net force of zero and the object remains at rest. An unbalanced force causes a change in motion.

Answer:

when an unbalanced force acts upon it
