Thank you!!
INTERACTIVE LECTURE DEMONSTRATION PREDICTION SHEET-ROTATIONAL MOTION Directions: Click here to download the Prediction sheet. Write your name at the top to record your presence and participation in these demonstrations. For each demonstration below, write your prediction on this sheet before making any observations. You may be asked to send this sheet to your instructor. Demonstration 1: A turntable is rotating counter- Draw V, and V2 here Draw Av here clockwise at constant angular speed. An object near the edge of the turntable remains there without slipping or flying off. The figure to the right shows the object at one instant (position 1) and then an instant later (position 2). On the picture, draw the object's velocity vector v, at position 1 and V2 at position 2. Then, in the space to the right, draw the vector that represents the difference of the two velocity vectors, Av = V2 - V]. Only after you have made your predictions, open the simulation Ladybug Revolution: https://phet.colorado.edu/sims/cheerpj/rotation/latest/rotation.html?simulation=rotation Drag the ladybug to the outside edge. Use the slider to set the Angular Velocity to about 60 rad/s. Observe the velocity and acceleration as the bug passes through position 1 and position 2. Compare the two velocities to your predictions and explain any differences. What is the direction of the acceleration relative to the center of the disk? Click here to see the vector subtraction. Compare the result to your prediction. Describe the direction of the vector AV relative to the center of the disk. How does this compare to the direction of the acceleration? Explain why. Demonstration 2: For the motion of the turntable described in Demonstration 1, sketch on the diagram on the right the net force acting on the object at the edge of the turntable when it is at position 1. What is the cause of this force? Only after you have made your prediction, click here to view the force. Compare the force to your prediction, and explain why the force must be in this direction to cause the described motionStep by Step Solution
