Key Stage 5
Meaning
The gravitational constant is a universal physical constant which is a measure of how easily a gravitational field propagates through space.
About The Gravitational Constant
- The gravitational constant is denoted with a capital G.
- The units of the gravitational constant are Newton metres squared per kilogram squared (\(Nm^2kg^{-2}\)).
- The gravitational constant has one of the greatest uncertainties of all physical constants from measurement as there is no way to shield an external gravitational field from interfering with the measurement.
