We all know that the Earth's gravity keeps us on the ground. But why can't we feel the gravitational force of other objects, like our friends or the chair we're sitting on?

The answer is that the gravitational force of other objects is very weak. The gravitational force between two objects depends on their masses and the distance between them. The Earth is very massive, so its gravitational force is strong enough to overcome the other forces acting on us, like the force of the chair pushing us up. However, the gravitational force between two objects with small masses, like humans, is very weak. It is so weak that we cannot feel it.

However, we can measure the gravitational force between two objects with small masses using very sensitive instruments. And we can use this information to learn about the universe and how it works.
