Repeating Time Period

DoNow: Three 10040 kg point masses are separated by a distance of 0.082 m and form an equilateral triangle. Determine the magnitude and direction of the attractive force at each mass and the acceleration any mass would experience at the center of the arrangement. Explain. (notes)

AIM: I can describe the variables and relationships in Newton's Law of Universal Gravitation and how the attractive force is related to acceleration and centripetal acceleration.
