I've been given the task of analysing data from an experiment where an object was dropped with an initial velocity of 0.I've calculated the time in s2 from the original milisec.
Distance Time s2
I was h =g x t2 /2
Which I rearranged to make g the subject g = 2h / 2
The Attempt at a Solution
I've calculated the gradient of the graph as 4.9 using (Difference y) / (Difference x)
Picking 2 points from the graph
I'm stuck at the point where it says "Show how the gradient is used to find a value for g"
Using the equation i've calculated g to be 9.8 but i'm not sure how this related to the gradient apart from being double the amount?
