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+at
v =u +2as
Key:
a = acceleration
s = distance
t = time
u = initial velocity
v = final velocity
I will be using the formulae s=ut+at to calculate gravity.
Assuming that u=0 I can rearrange the formulae like this:
S=at
Therefore a=2s
Plan
My experiment will involve the use a clamp stand, 2 light gates and a marble. I will set up a clamp stand that holds 2 light gates, which will hold 1 light gate near the floor, and the second light gate various distances away. These distances will be 0.500m, 0.830m, 1...
