Step-by-Step Guide to Centripetal Acceleration Lab

Let's gather all the materials needed for our centripetal force experiment.Before we begin assembly, inspect all materials carefully for any damage that could affect the experiment.Take the string and carefully thread it through the glass tube. Ensure it moves freely without catching.Securely tie the rubber stopper to one end of the string. Double-check the knot to ensure it's tight.Using the meter stick, measure the length from the bottom of the tube to the center of the stopper. This is your radius for calculations.Now, let's review important safety considerations before we begin the experiment.Ensure you have a clear workspace with a two-meter radius. Remove any breakable objects from the area.Always wear safety goggles during the experiment, and regularly check the string for signs of wear.Your workspace should look like this, with a clear area extending two meters in all directions from the center point.With our equipment properly set up and safety measures in place, we're ready to begin our experiment.First, hold the glass tube vertically, ensuring it's perfectly straight.Begin swinging the stopper in a horizontal circle. Try to maintain a constant speed and uniform circular motion.Using a stopwatch, time exactly twenty complete revolutions. Start timing from a specific point in the circle.To find the period of one revolution, divide the total time by twenty.Finally, calculate the average period from all three trials to ensure accuracy.
