Experienced physics students always do the same thing whenever they write down an answer to a question: check the units. If the units are wrong, you know you've made a mistake! That way, you can catch your own errors and elevate your grade.

Lesson 9 (Work and Energy) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you!

Exercises in this video:
1. A rocket pushes a space cow, from rest, with a Force of 100N, over a distance of 10m. How much work did the rocket do? What is the final kinetic energy of the cow? How fast is the cow moving?

2. You lift a 10kg cow, with a constant velocity, 10m up. How much work did you do? How much potential energy is stored in the gravitational field?

3. You drop the cow 10m onto a big cow airbag. How fast was the cow moving right before she hit the airbag? How fast would a cow with twice as massive be moving with the same setup?

4. A giant wrecking ball with 80kg mass, is dropped from a height of 35m. It bounces off of a trampoline and reaches a height of 14m on the return trip. How much energy was lost to heat in the bounce?

5. A square cow slides down a frictionless ramp, starting at a height h above the ground. At the bottom the cow starts sliding along the ground. How far does the cow slide, in terms of m, g, h, and u, where u is the coefficient of friction between the cow and the ground? [u is mu]

Special thanks to Mark Rober for his encouraging shoutout and to Simone Giertz for letting me almost hit myself in the face with a bowling ball at her workshop.

Lesson 17 (Waves, Light, and Sound) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need a review of AP Physics concepts before the exam? This course is for you!

Exercises in this video:
1. You measure an oscillating wave to have a wavelength of .5m and a frequency of .5Hz. What is the speed of the wave in that medium? What would the wavelength of a wave with frequency 2.5Hz be?

2. You tune your car radio to your favorite station, 93.5 on the dial. That’s a frequency of 93.5MHz. What is the wavelength of that radio wave?

3. At sea level, the speed of sound in air is around 343m/s. The speed of light in air is about 3.00x10^8m/s. If you are watching a rocket launch 11km away, what will be the difference between the time you see the launch and the time you hear it?
