a body remains at rest or in motion with a constant velocity unless acted upon by external force.
All of them
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
whats newston's 2 law of motion
Newton's third law of motion is that for every action there is an equal and opposite reaction. This law is also called reciprocal motion/force or "action-reaction."
the law of inertia
Gravity
Newton proposed three laws of motion. Newton's 1(first) law of motion-A body continues to be in the state of rest or motion until and unless an external force is applied to change its state.
Newtons laws of motion
Balanced forces keep object in its state of motion (moving or at stop). An objects state of motion can be altered when it is subjected to an unbalanced force. This reflects Newtons first law of motion.
Isaac Newton, he discovered: -Newton's First Law of motion. -Newton's Second Law of motion. -Newton's Third Law of motion.
