Orders of magnitude (force)
From Wikipedia, the free encyclopedia
The following list shows different orders of magnitude of force.
Since weight under gravity is a force, several of these examples refer to the weight of various objects. Unless otherwise stated, these are weights under average Earth gravity at sea level.
