You stay on the earth. Without it you would fly off into space and die because the atmosphere will be too thin to sustain life.

Relative gravitational potential energy.
U = m g h Where U is Gravitational Potential Energy (measured in Joules) m is Mass (measured in kilograms) g is Gravitational Acceleration (~9.8 meters/second2) h is height (measured in meters)
Mostly it is not used every day.
Prime example of radiation in our every day life is the heat we get from the sun (mostly radiation heat)
PE = mgh gravitational potential energy = mass x gravity x height The corresponding SI units are: joules = kg x 9.8 N/m x meters (Gravity is 9.8 N/m, equivalent to 9.8 m/s2.)
