Helllooooo! Try these wave problems.

# APPhysics

# How Fast is Sound?

Click the link below to download a video of Emma and her friends clapping.

**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?

# Simple Harmonic Motion

IT”S FRIDAY!!!!!

Working with a buddy, try these two problems:

- Kinetic Energy to Oscillation
- Masses and Springs –
**TURN FRICTION OFF**when running this- What is the mass of the Red Mass?
- What is the mass of the Green Mass?
- What is the gravitational field strength on Planet X?

# Rotation Direct Measurement Video

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
must have been applied to accelerate the disk?**torque** - What
was provided by the rocket motor?**force**

- Use the video and video analysis to show that angular (rotational) momentum is conserved (or not…)

# Rotational Motion Aviaries

Try these three problems:

# Circular Motion and Gravity Partner Quiz

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.

**Physics Aviaries**

**Direct Measurement Video**: Einstein Riding the Graviton (you’ll have to * download *the video first)

**pHet Gravitational Force Lab: **

Click here for the lab. After taking a bunch of data points, create a graph that will allow you to find the universal gravitational constant

# Impulse and Momentum Problems!!

Complete these three scrumptious PhysicsAviaries before you work on your egg cars.
