b. Change the Frame Rate in cell F1 from 25fps to 30fps (preparing for analysis of your own data). How does changing the frame rate affect the the data's timepoints? c. You will always have the option to copy and paste your exact time values from the Tracker output, instead of using the formula. Describe in your own words the logic behind this formula for generating the timepoints. Slide 4 - Experimental Analysis Preparation: Computing Velocity Results: a. Click on the first velocity data point, and look at the formula bar. What information has been used to calculate the velocity value? b. Describe, in your own words, the physics relationship that is being used to transform position and time information into velocity information. C. Is this calculation an average velocity, an instantaneous velocity, or does it use elements of both? Justify your response. (hint: from an experimental perspective, we are doing our best to create a derivative, but we are inherently limited in real life when we take sample measurements at finite intervals)
