According to the material, increasing the force acting on an object generally causes what to happen to the change in motion?

• A. The change in motion decreases.
• B. The change in motion increases.
• C. There is no change.
• D. It reverses direction.

Answer: (B)

When a force acts on an object, it changes the object's motion, which we call acceleration. The size of that change depends on the force and the object's mass: acceleration = net force ÷ mass. So, for a given mass, increasing the force makes the acceleration bigger, meaning the change in motion happens more quickly. If you push harder in the same direction as the motion, the object speeds up faster; if you push opposite, it slows down faster. In short, more force generally means a larger change in motion.
