Explanation Formula used: W = f d cos θ W = F d c o s θ W = work done d = displacement θ = angle between force F and displacement d Calculations: The wok done is given by W = f d cos θ Here the force F is the centripetal force and that acts along the radius of the circle towards the center. The displacement of the object in circular motion at any point is along the tangent to the circle at that point

1. Measurements and Linear Regression 1.1 Introduction The objective of this lab assignment is to represent measurement data in graphical form in order to illustrate experimental data and uncertainty visually. It is often convenient to represent experimental data graphically, not only for reporting results but also to compute or measure several physical parameters. For example, consider two physical quantities represented by x and y that are linearly related according to the algebraic relationship, y=mx+b, (1.1) where m is the slope of the line and b is the y-intercept. In order to assess the linearity between y and x, it is convenient to plot these quantities in a y versus x graph, as shown in Figure 1.1. Datapoints Line of regression Figure 1.1: Best fit line example. Once the data points are plotted, it is necessary to draw a "best fit line" or "regression line" that describes the data. A best fit line is a straight line that is the best approximation of the given set of data, and…
