Homework Statement
Hi, I recently preformed a ticker timer experiment in my grade 11 physics class, and I seem to be having a bit of trouble with the assignment.
Our results were recorded as follows.
Time (s)|Distance (cm)
0|0
0.1|6.15
0.2|21.35
0.3|43.15
0.4|71.55
I am supposed to create a d-t graph which I have done, and then create a v-t graph and a-t graph. I am having troubles getting from the d-t graph to the v-t graph. I am aware of using the tangents of each points, but I cannot seem to do this correctly, as my results are always incorrect. So I need to find a way to find the instantaneous velocity for each time segment, that way I can plot the v-t graph.
Homework Equations
I am not positive which equations can be used, other than the tangent method, but as I previously stated, I am doing this incorrectly and would greatly prefer an equation (if possible) for the instantaneous speed.
The Attempt at a Solution
I have tried finding the instantaneous velocity by using v = d/t (for example, v = 6.15/.1) but this does not work either because when plotted, the graph is always a curve.
Also, if I were to calculate the acceleration from my results. Would I calculate the average velocity, then divide that by t2 - t1?
Thanks for any help, it is greatly appreciated. Also, I am sorry if I used the template incorrectly, this is my first time posting here.
