1. If the center of our moon is 384,400,000 m away from the center of Earth, how much force is needed to keep the moon in orbit around Earth? We previously found the moon to be moving at 1020 m/s relative to Earth and the mass of the moon is 7.35 x 10^22 kg. • Speed in a circle - m/s, how fast... • Radius - m, distance from the center of the circle to the object moving in the circle • Mass - kg, how much stuff something is made of • Centripetal Force - N, the force needed to keep an object moving in a circle Which variable is 1020 m/s?
