Newton's second law of motion

Newton's second law of motion states that the force acting on an object equals its mass times its acceleration (F = ma). This means that the more force you apply, the faster an object accelerates; and heavier objects require more force to change their speed or direction. Essentially, it explains how the amount of force relates to the movement of an object, linking the cause (force) to the effect (acceleration). This law helps us understand everything from why heavier objects are harder to start or stop moving to how engines produce motion.
