The gravitational field strength at the surface of Saturn is approximately 10.4 N/kg.
Define gravitational field strength.
State one factor which causes the difference between the gravitational field strength at the surface of Saturn and the gravitational field strength at the surface of Mars.
State and explain the difference between the orbital speed of Saturn and the orbital speed of Mars.
