One of the most suprising things we learn in Physics class is that the acceleration due to Earth’s gravity is constant for any mass (9.81 m/s/s). Gallileo demonstrated it in 1589 by dropping objects of different mass from the Leaning Tower of Pisa. Sure, a heavier mass will do more damage, but they all reach the ground at the same time. One explanation […]
