Lesson 19 (Voltage, Resistance and Current) 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. If you connect 10 AA batteries, each with a voltage of 1.5V, in series, what will be the total voltage of the resultant battery pack?
2. What would be the voltage if you connected them in parallel?
3. If you shoot an electron across a potential of 1000V, how fast will the electron end up going?

![Work and Energy - Physics 101 / AP Physics 1 Review with Dianna Cowern
Lesson 9 (Work and Energy) of Diannas 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.
