===About Gravitational Field Strength===
: On [[Earth]] '''gravitational field strength''' is roughly 10 [[Newton]]s for each [[kilogram]] of [[mass]] (10N/kg).
: Different [[object]]s have different '''gravitational field strengths'''.

===Meaning===
'''Gravitational Field Strength''' is the [[force]] on an [[object]] per [[kilogram]] in a [[Gravitational Field|gravitational field]].
===About Gravitational Field Strength===
: At [[Sea Level|sea level]] on [[Earth]] the '''gravitational field strength''' is 9.8 [[Newton]]s for each [[kilogram]] of [[mass]] (9.8N/kg).
'''Gravitational Field Strength''' depends on:
*The [[mass]] of the [[moon]], [[planet]] or [[star]] - The larger the [[mass]] the greater the '''gravitational field strength'''.
*Distance from the [[Centre of Mass|centre of mass]] of the [[moon]], [[planet]] or [[star]] - The larger the [[distance]] the smaller the '''gravitational field strength'''.
