How can the angular acceleration remain constant in experiment 4 despite the changing direction of the ladybug?
Added by Jose J.
Step 1
Angular acceleration is the rate of change of angular velocity with respect to time. It is a vector quantity that describes the change in the rotational speed or direction of an object. Show more…

Click "Reset All" again and this time drag the Beetle on the turntable and put it at (3,0). Set the angular velocity of 100 degrees/s. Now click "Go" and stop it after the turntable rotates twice. Make sure you did click on θ,ω,v graph to answer the following questions a. What are the values you read after it completes its rotation Ladybug: θ = 721.25 degree, ω = 100 degrees/s, v = 3.491 m/s Beetle: θ = 720.89degree, ω = 100 degrees/s, v = 5.344 m/s b. Click on "radians" and write the values you read Ladybug: θ = 12.59 rad, ω = 1.745 rad/s, v = 3.491 m/s Beetle: θ = 12.58 rad, ω = 1.745 rad/s, v = 5.344 m/s c. What are the angular and centripetal accelerations Ladybug: aR = ___ m/s², α = ___ rad/s² Beetle: aR = ___ m/s², α = ___ rad/s²

Ladybug Revolution Consider the statement: “All points on a rigid object have the same angular acceleration and angular speed.” Is the angular displacement also the same for all points or does it differ? Explain your reasoning.. How is tangential speed represented in Ladybug Revolution? Do all points on a rigid object have the same tangential speed? We have learned about three types of acceleration. Describe how the simulation can be used to find each for the bugs in Ladybug Revolution.

A ladybug crawls along the radius of a rotating disk of mass M = 0.024 kg and radius r = 0.06 m (I_disk = 1/2 Mr^2). The pivot is frictionless and the disk is initially rotating with angular speed ω_A = 31.416 rad/s. The ladybug starts at the outer edge (Figure A) and ends at center (Figure B). At the end of the ladybug's travel the disk rotates with angular speed ω_B = 31.604 rad/s. Figure A Figure B For this system angular momentum is conserved because (a) the ladybug has a very small mass compared to the disk. (b) there are no external torques acting on the system. (c) angular momentum is always conserved.
