Making Sense of Data Aim: To calculate acceleration due to gravity (g) using the results of time and distance provided. Theory: Acceleration due to gravity is 9.81 ms-2, which is a constant. I am going to use laboratory results carried out by my teacher to calculate g. The equations that relate distance, time, initial velocity, final velocity and acceleration are: v=u+at s=u+v t 2 s=ut+½at ² v ²=u ²+2as Key: a = acceleration s = distance t = time u = initial velocity v = final velocity I will be using the formulae s=ut+½at ² to calculate gravity. Assuming that u=0 I can rearrange the formulae like this: S=½at ² Therefore a=2s Plan My experiment will involve the use a clamp stand, 2 light gates and a marble.
