Here's why:
* Newton's Third Law: For every action, there is an equal and opposite reaction. When you push against the ground, the ground pushes back on you with the same force.
* Mass and Acceleration: The amount of acceleration an object experiences is inversely proportional to its mass. This means that the more massive an object is, the less it will accelerate for a given force.
* Earth's Immense Mass: The Earth is incredibly massive. When you push against it, the force you exert is minuscule compared to the Earth's total mass. As a result, the Earth barely accelerates.
In essence, you are pushing against a giant, unyielding object. While you experience the force of the Earth pushing back on you (which propels you forward), the Earth itself experiences virtually no change in motion due to your small force.
