A classic example of Newton's second law of motion in action is the comparison between pushing a small car and a large truck.
If you apply the same force to both vehicles, the smaller car (which has less mass) will accelerate more than the larger truck (which has more mass). According to Newton's second law, which is expressed as \( F = ma \) (where \( F \) is force, \( m \) is mass, and \( a \) is acceleration), if you want to achieve the same level of acceleration with the larger truck as you do with the smaller car, you'll need to exert a greater force due to its larger mass.
Another practical example can be seen in sports: consider two athletes, one a lightweight runner and the other a heavyweight shot putter. If both were to push off the ground with the same amount of force when starting a sprint, the lighter runner would quickly accelerate ahead due to having less mass, while the heavier shot putter would have a slower acceleration because more force would be needed to move his greater mass.
This illustrates the principle that larger objects require more force to achieve the same acceleration as smaller objects.
