Classic footage of the Apollo 11 astronauts show them takinglarge leaps bounding around the surface of the moon. Bytransporting this simple spring and mass system to the moon, we canmeasure the gravitational force exerted by the moon on objects atits surface and compare it to the force of gravity exerted by theearth on people at its surface.
i. Use the apparatus to measure the force of gravity exerted by themoon on the 50 gram mass. What is the value of this force?
ii. If this mass is dropped from a height of 10 m, at what ratedoes this mass
accelerate towards the surface?
iii. If you can jump to a height of 2 feet on earth, explain usingenergy principles why the change in gravitational force enables youto jump much higher on the moon.
