The Apollo 15 test of Galileo’s ball dropping experiment, on the moon.

Little did Galileo dream that his famous experiment would be tested on the moon some day. The experiment once again “proved” that gravity causes objects of different weights to accelerate at the same rate, as they fall.

For some mysterious reason gravitational mass acted differently then inertial mass. Newton explained it by saying gravity and inertia are proportional, Einstein was fooled completely by gravity. He said since a falling body feels nothing as it is falling, (it is weightless) that gravity is not a force. Bodies warp space and follow geodesic lines.

Actually gravity is a force, in the case of Galileo’s experiment or the moon experiment it is the protons that are falling under the force of gravity alone – it doesn’t matter if they are part of a feather or a hammer – they will all accelerate at same rate since the protons all have the same mass. Gravitational mass is just a special case of inertial mass.

GRAVITY ALONE, IS ACTING ON ALL THE NUCLEONS (PROTONS) OF THE BODY SIMULTANEOUSLY. THE PROTONS ALL HAVE THE SAME MASS SO THEY WILL ALL ACCELERATE AT THE SAME RATE. – THEREFORE NO STRESS IS PRODUCED, THE BODY IS WEIGHTLESS.
