Deduce Newton’s first law of motion from Newton’s second law of motion.

Newton’s second law states that force is equal to the rate of change of momentum (F = ma). If no external force acts on a body (F = 0), then acceleration (a) is also zero. This means the object remains at rest or in uniform motion, which is Newton’s first law.
