according to newton’s 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 newton’s 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 just decrease to zero. Equal action - reaction forces act on different objects and balanced forces (equal and opposite forces on one object) keep it at rest or in uniform motion. An unbalanced force causes a change in motion.

Answer:

when an unbalanced force acts upon it
