CIRCUITS
Trying to remember how all the variables add can be really confusing when you're working with complicated circuits. Here is a simple list of how they all add up in series vs in parallel!

Kirchhoff's Rules
Here's a great example video of how to use Kirchhoff's loop and junction rule. In general here are the equations:
Around a single loop: ΔV = 0
At a junction : Iin = Σ Iout

Physics 2B/4B Practice Problems
This practice worksheet goes over 1D and 2D kinematics, calculating the force on a point charge caused by several charges, and a mixture of kinematics and electrostatic forces.
The answers are on the bottom of the final page upside down for you to check your work!

UNder pressure?
Watch this video to relieve some of that stress and learn more about "Absolute & Gauge Pressure"! This is a topic you should be seeing if you are in PHYS 2a or 4a. If you are confused about any other topic, we highly recommend Organic Chemistry Tutor on YouTube as a resource.
1st Law of Thermodynamics
The First Law of Thermodynamics is crucial to understand since it allows for the calculation of various parameters such as work and energy. For those with chemistry under there belt, you may notice a slight difference in how the equation is set up. The attached video provides an explanation of the law and why the equation varies from a "chemistry" and "physics" perspective.
