Activity for practicing plotting graph data points, drawing a line of best fit, calculating a gradient and analysing the line in order to calculate quantities. The first page includes the activity for students to complete and the second page includes solutions to the questions. Suitable for AQA and OCR Physics A AS-Level and A-Level specifications.

This is part of a series of worksheets for practicing different graph skills. Graphs Skills worksheets 1 & 2 are available for free, subsequent worksheets are premium resources.
This worksheet is great for home learning since it has solutions to all questions included in the document and it is part of a series that gradually builds up a range of graphing techniques.
14 September 2024: It was brought to my attention that the data provided an invalid intercept value for analysis if imported into a spreadsheet to compute. I realised that two values for s suffered from typos (u=12 had s=35 and u=14 had s=42). These data give a negative intercept preventing correct analysis. The values have been corrected (u=12 had s=34 and u=14 had s=43). This affected the values in the tables, however, the values plotted on the grid were correct.

If the data used in this exercise is plotted digitally (in excel or using a graphing calculator) then the y-intercept is negative giving an imaginary solution for the velocity. This only works with a poorly drawn line of best fit which then gives a positive y-intercept.
thank you!!
Thanks. Very helpful
