Forces cause accelerations, and thus velocity. Using Newton's Law of Gravitation, the GM orbital velocity (speed) of an object can be shown to be: v=. R Where M is the mass of the body being orbited and R is the average distance from the body. A) Calculate Earth's orbital velocity around the Sun.. B) How fast is Earth traveling in m.p.h.? C) Calculate Earth's orbital velocity using a second method. (Hint: The Earth orbits the Sun in approximately a circle every 365 days. Speed = Distance/Time. Distance = the circumference of Earth's orbit = 2nR and Time is number of seconds in a year.) D) Compare the orbital velocities (speeds) from Parts A and C by calculating the percent difference of the two velocities and comment (are they about the same?). %3D
