58 Force of a Spring Hang a spring vertically and measure the stretch of the spring as a function of mass added to the spring. Do not exceed 250 g mass. Take 5 points. Use Newton’s Laws to find an expression for the force of the spring in terms of the mass, m , added. Make a plot (by hand!) of the force of the spring versus the stretch on the supplied paper. Each person should make a graph . One goal of this exercise is to ensure that you can quickly make a graph by hand when needed. First decide what “force versus stretch” means. Which variable goes on the horizontal axis, and which on the vertical axis? Second , decide on the ranges of the variables, i.e. the maximum minus minimum value for each variable. Third , examine the graph paper supplied (a coarse graph paper) and choose a scale for each axis. Fourth , make tick marks on the axes and label them with values. Also label the axes with the variable and the units. Give a meaningful title to your graph.
