Problem

When you stand still on the ground, how large a force does the ground exert on you? Why doesn't this force make you rise up into the air?

Solution 17Q: Why does the force exerted by the ground on us is not pushing us in the air, and what is the magnitude of this force, this we will understand in the problem. Step 1 of 2 Concept: Newton’s second law: The force F acts on mass m produces an acceleration a in the object. Mathematically, F=ma Newton’s third law: To every action, there is an equal and opposite reaction.
