Im trying to figure out gravitational forces exerted by the sun and the moon...HELP
You have to use this formula: F=G*M*m/d^2, where G=Gravitational constant, M=Mass of the bigger object, m=Mass of the smaller object and d=Mean distance between the two bodies.
P.S. You have to look up ALL these values from a variety of sources, such as "Planetary Facts Sheets". You have to Google it.
