Period of a Pendulum GIZMOS

Document Content and Description Below

Student Exploration: Period of a Pendulum Vocabulary​:​ controlled experiment, mean, pendulum, period Federalism, mode of political organization that unites separate states or other polities wit... hin an overarching political system in a way that allows each to maintain its own ​integrity​. Federal systems do this by requiring that basic policies be made and ​implemented​ through negotiation in some form, so that all the members can share in making and executing decisions. ​Prior Knowledge Questions ​(Do these BEFORE using the Gizmo.) A ​pendulum​ ​is a weight that can swing freely back and forth. The ​period​ ​of a pendulum is the amount of time required to make one full back-and-forth swing. In each of the comparisons below, circle the pendulum that you think will have a ​shorter​ period. Long pendulum vs. Short pendulum Heavy pendulum vs. Light pendulum Pendulum on Earth vs. Pendulum on Moon Pendulum with a large arc vs. Pendulum with a small arc Gizmo Warm-up The ​Period of a Pendulum ​Gizmo™ allows you to explore the factors that control how quickly a pendulum swings back and forth. To begin, practice measuring the period of the pendulum. On the Gizmo, check that all variables are set to their original values: m​ = 0.5 kg, ​L​ = 2.0 m, ​g​ = 9.8 m/s​2​, and ​θ​ = 20°. Open the ​Tools tab and drag an arrow so that it just touches the pendulum at its left-most position, as shown at right. 1. A full “swing” of the pendulum is one complete back-and-forth movement. Select the TABLE tab. Click ​Mark time​ each time the pendulum touches the arrow. Mark 10 times. What values do you get for the period of the pendulum? ___1.14___ ___1.56___ __2.03____ _2.90____ _3.16_____ __3.46____ __4.17____ __5.21____ __6.95____ __7.56____ [Show More]
