Pam observed many small earthworms in the backyard of her house after a heavy rain. What most likely formed the earthworms?

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?

What are the differences and relationships between speed, velocity, and acceleration
