Final answer:
The correct formula to find force is force = mass x acceleration, which is Newton's second law of motion.
Step-by-step explanation:
The formula to find force is force = mass x acceleration, which is commonly referred to as Newton's second law of motion. This means that a force applied to an object will produce an acceleration proportional to the mass of the object. The formula emphasizes that force is a vector quantity, meaning it has both magnitude and direction. Forces can cause a variety of changes in the motion of an object, including starting it moving, changing its speed or direction, or causing it to stop.
