Gravitation

The term “freefall” refers to when an item descends towards the Earth due to the Earth’s gravitational force. Previously, it was assumed that lighter bodies would fall slowly while heavier bodies would fall quickly. For example, if a feather and a metal coin were dropped from the same height, the metal coin would reach the […]

When an item falls towards the earth due to the gravitational force of the earth, it is referred to as freefall.

A space elevator is a hypothetical structure for transporting materials from a surface of a celestial object through space. The term is most commonly used to describe a structure that extends from the Earth to the geostationary orbit. Beanstalks, sky bridges, space elevators, space staircases, skyhooks, orbit towers, and orbital elevators are all names for

In simple terms, the buoyant force is exerted in the upward direction by any liquid when a body is immersed in it. It is always an upward force because the pressure of any fluid increases with depth. Archimedes’ principle happens to be the buoyancy or buoyant force exerted on a body immersed in the liquid.
