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

according to newtons first law of motion, when will an object at rest begin to move?\nwhen its inertia decreases to zero\nwhen an unbalanced force acts upon it\nwhen the action and reaction forces are equal\nwhen 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 be zero for a real - world object. Equal action - reaction forces act on different objects. Equal and opposite forces on an object balance each other and keep it at rest. An unbalanced force will change the object's state of motion.

Answer:

when an unbalanced force acts upon it
