INVESTIGATION OF THE FACTORS AFFECTING THE TIME PERIOD OF A SIMPLE PENDULUM I will begin with an explanation of motions and Galileo's discovery of motion under gravity: Galileo's insight was that all bodies fall equally fast in a gravitational field. "Falling in space,"" means simply following the orbit under gravity. There is no need for this "falling" to be straight down since there is no up, down or any point of reference in space. Gravity can be cancelled in this way by free fall because the effects of a gravitational field are just like those of acceleration. Indeed if you...
