Which force is responsible for holding objects against the Earth?

The gravitational force is the key interaction responsible for holding objects against the Earth. This force is a fundamental natural phenomenon that attracts objects towards one another based on their masses. In the context of the Earth, it pulls everything towards its center, which is why we stay grounded and why objects fall when dropped.

Gravitational force acts over long distances and is always attractive, meaning it draws masses together rather than pushing them apart. It is crucial for various natural processes, such as the orbits of planets and moons and the formation of tides due to the moon's gravitational pull on Earth.

Other forces listed, such as the electromagnetic force, nuclear force, and frictional force, play different roles in nature but do not hold objects against the Earth in the same way. The electromagnetic force governs interactions between charged particles and can cause materials to stick together or repel each other, but it does not primarily hold objects against the Earth. The nuclear force operates at the subatomic level, binding protons and neutrons in atomic nuclei, and is not relevant to macroscopic interactions with gravity. Frictional force involves the resistance encountered when two surfaces interact, which can help keep an object in place on surfaces, but it is the gravitational force that primarily ensures that all
