1. The problem statement, all variables and given/known data I won't need to give the detail, i just want to know an example of a diagram like the one I need to draw: Q: An experiment is performed to track an object under the influence of a constant force. At regular intervals the position of the object is measured. (The data is displayed in the table) So first we had to plot the data in the graph and draw a best fit curve thought the data (It's a x(m) vs time(s)) plan... I've done that, the part I'm confused about now is What are "error bars"?? it said "Make sure to include the error bars. And the 2nd part: To experimentally determine the acceleration of the object you need to re-plot the data in a different form. Determe what the plot should consist of (x vs ?) and create the new plot on the next page (We're given a 100% bank graph paper except for x(m) axis). And how do determine new errors, or errors at all??? 2. Relevant equations None, there won't be any 3. The attempt at a solution I don't suppose it would be anything looking like a best fit curve, would it?
