Make a graph from this video to calculate the speed of sound.
Based on your graph, which student is having the hardest time keeping in time with the beat? How can you tell?
You’ll need to download the videos first and then input them into
- What is the moment of inertia of the disk?
- What is the final angular velocity of the disk?
- What is the average angular acceleration while the rocket is firing?
- How long was the rocket firing for?
- What average torque must have been applied to accelerate the disk?
- What force was provided by the rocket motor?
- Use the video and video analysis to show that angular (rotational) momentum is conserved (or not…)
Using your brain, your partner’s brain, your notes, your partner’s note, your calculator, your partner’s calculator, your pen, your partner’s pen and a gluten-free blueberry muffin (if available) complete the Circular Motion and Gravitational Force Partner Quiz.
