Newton's laws of motion
牛頓運動定律

Newton's first law of motion
Every object remains in a state of rest or uniform speed along a straight line unless acted on by a net force.

Newton's second law of motion
The acceleration a of an object is proportional to, and in the same direction as, the net force F acting on it, and inversely proportional to the mass m of the object.

Newton's third law of motion
To every action there is an equal and opposite reaction. This law applies to two objects interacting with one another.
