classic footage of the Apollo 11 astronauts show them taking large leaps bounding around the surface of the moon. By transporting this simple spring and mass system to the moon, we can measure the gravitational force exerted by the moon on objects at its surface and compare it to the force of gravity exerted by the earth on people at its surface. i. Use the apparatus to measure the force of gravity exerted by the moon on the 50 gram mass. What is the value of this force
