WebChapter 12 mp. If you launch a projectile upward with a high enough speed, its kinetic energy is sufficient to allow it to escape the earth's gravity−it will go up and not come back down. Given enough time, hydrogen and helium gas atoms in the earth's atmosphere will escape, so these elements are not present in our atmosphere. WebEventually, there will be an equilibrium of the upward buoyant force and the downward gravitational force, where the Helium molecule will remain if left alone. However, there are forces at work that can allow Helium to escape the atmosphere. The main one seems to be heat from the Sun. Obviously, the Sun heats the atmosphere.
