2. 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 = 2tR 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 »Earth M (Sun)

2. 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=
VR
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 = 2TR 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?).
