according to newtons first law of motion, when will an object at rest begin to move?\no when its inertia decreases to zero\no when an unbalanced force acts upon it\no when the action and reaction forces are equal\no 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 and can't decrease to zero for a real - world object. Equal action - reaction forces act on different objects. Two equal and opposite forces on an object are balanced and won't make it move. An unbalanced force will change the object's state of motion.
Answer:
when an unbalanced force acts upon it
