Generally the __________ the force acting on an object, the greater the change in motion.

Generally the __________ the force acting on an object, the greater the change in motion.

• A. Lesser
• B. Greater
• C. Equal
• D. Only

Answer: (B)

When a bigger force acts on an object, the change in its motion is greater. This happens because force causes acceleration, and for a given mass, accelerating is directly proportional to the force applied (a = F/m). So pushing harder makes the object speed up or slow down more quickly, resulting in a larger change in motion. If the mass were larger, the same push would change the motion less, which helps show why more force leads to a bigger change.
