Im doing a coursework based on the viscosity of Godlen syrup at the momement. I have got my results and have plotted a Distance Time graph for each of my 4 different ball bearings that were dropped through syrup.(adsbygoogle = window.adsbygoogle || []).push({});

Now my first question is do i have to join the points up with a curve and then do a line of best fit or do i just draw a line of best fit, or do i just draw the curve?

Secondly i need to work out terminal velocity from this graph, does that mean the maximum velocity the ball bearing has reached during my graph? and if so then i will just need to use the tangent to work out the maximum gradient point right?

thanks for the help
