Part 1. Mass Variation Objective: Determine the effect of the mass of the pendulum on its frequency while we keep constant the length and amplitude (8). Results Table 1. Simple Pendulum Mass variation {length = 1.00 m and 6 = 15) 1. Using Excel, plot the mass (m) (x-axis) and frequency (Qw-axis). To a proper analysis of the data, you need to change the yaxis scale of your graph. Follow these steps: -Rightclick on the yaxis. -Select format axis, -On the right side of the screen appear \"format axis window". -In axis options, aw: Q and maximum: 1 Explain in detail Part 2. Amplitude (angle) variation Objective: Determine the effect of the amplitude (0) of the pendulum on its frequency while we keep constant the length and mass. Results Table 2.

To set up the angle (amplitude), by clicking on the blue mass and dragging it to 0 = 15 4. In the following picture, you can see where you can set up the length, mass, gravity (which (amplitude- 0 = 15, it is a constant value through all Part 1 of the experiment). will be Earth's gravity in our experiment), angle (amplitude), and activate the stopwatch. Release the mass and using the stopwatch measure the time taken for 5 oscillations (n = 5) (back and forth). Complete three trials (t1, t2, and ts).
