* Weight vs. Force: Weight is the force of gravity acting on an object's mass. When a person stands still, the force they exert on the ground is equal to their weight.

* Walking Dynamics: When walking, a person's foot pushes off the ground to propel them forward. This push requires a force greater than their weight. This is because the force must not only counteract gravity but also provide the acceleration needed for movement.

Think of it this way: If you were to stand on a scale, the reading would be your weight. If you then start walking, the reading on the scale would momentarily increase as your foot pushes down with greater force to move you forward.
