Moment of Inertia Gizmo | Student Exploration: Moment of Inertia (GRADED A)

Document Content and Description Below

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Student Exploration: Moment of Inertia Vocabulary: angular velocity, line... ar velocity, moment of inertia, rotational kinetic energy, translational kinetic energy Prior Knowledge Questions (Do these BEFORE using the Gizmo.) At the finale of her routine, a figure skater starts to spin slowly in the middle of the ice rink, her arms and legs artfully outstretched. 1. What will happen as she stands up straight and pulls her arms in? 2. Why do you think this will happen? Gizmo Warm-up The Moment of Inertia Gizmo allows you to explore the factors that affect how quickly objects spin. The Gizmo shows a weightless turntable with several pegs. You can place the purple 1-kg masses on any of the pegs. When the Gizmo opens, there is a single 1-kg mass located 5 m from the center. 1. Click Play ( ). What happens? 2. The speed of rotation is described by angular velocity (ω), which is measured in radians per second. There are 2π radians (6.28 radians) in a circle. 3. Click Reset ( ). Move the mass so that it is only 1 meter from the center (r = 1). Reproduction for educational use only.

This is due to the fact that the center of mass is centrally located in the middle. The table spins. What is the current angular velocity? ω = 4 rad/s A. Click Play. What is the angular velocity now? ω = 20 rad/s B. How is this situation similar to a spinning [Show More]
