Galileo's Rolling Ball experiment Aim: Galileo in his rolling ball experiment investigated the acceleration of a ball rolling down an inclined plane, using a similar setup I will investigate how the time taken to roll down the inclined plane varies with the vertical height change. Theory: When two similar objects are thrown vertically downwards, they are in a state of free-fall. Both objects will hit the ground simultaneously; the force which causes these objects to fall down is the pull of gravity which is also the acceleration of these objects. As the object falls down, its speed increases hence its acceleration increases. Using the equation of motion; S= u t + 1/2 a t2 Since u = o, we can ignore initial velocity so: S = 1/2 a t2 Straight line equation: y = m x + c The variables in this experiment are: S and t2 When compared with the straight line equation: S = 1/2 a t2 y...
