Quick Overview on Energy, Work, and Force
In mechanics, there is sometimes several ways to model a system. In PHYS 2A and 4A you will learn Newton's equations which use forces to explain the system. You will also learn a way to solve a system using work and energy. If you get confused, this video is a simple and quick overview on the three quantities and how they relate to one another!

Kinematic Equations
Here is a helpful link for the different kinematic equations
Revised by Sarkis Tatarian
Formulas are your friends, use them.
Hey physics 2A and 4A students, you guys should be starting or getting close to starting kinematics.
There are multiple kinematic equations and it is difficult to see which one should or should not be used.
When starting any physics problem always write have a check list of ;
What the question is asking for
What you have
What you do not have
A diagram of the what the problem is asking for
When you have this list, you guys can figure out what equation should be used
X = displacement
a = acceleration
t = time.
vf = final velocity
vi = initial velocity
a) ΔX=vit + 1/2 at2
Has displacement, time, acceleration, and initial velocity
Doesn't have final velocity
b) (vi +vf)/2 = X/t
Has displacement, time, final velocity , and initial velocity
Doesn't have acceleration
c) a = (vf - vi)/t
Has acceleration, time, final velocity , and initial velocity
Doesn't have displacement
d) vf2 = vi2 + 2aΔX
Has acceleration, displacement , final velocity , and initial velocity
Doesn't have time

Physics 2A/4A Kinematics Mock Exam
This mock exam covers many of the topics from the kinematics portion of Physics 2A and 4A. To use this exam, set up an exam like environment and set a time limit for yourself. Good luck!

Read! Read! Read!
"There is a great deal of difference between an eager man who wants to read a book and the tired man who wants a book to read." –Gilbert K. Chesterton
Watch this video for great tips about how to improve your reading skills!
Shared by Kiran Gill
Fresno State research regarding reading strategies demonstrates that a majority of students feel that it is essential to be able to comprehend what you're reading to be considered a good reader. But in order to ensure that students understand what they are reading very special skills must be implemented!
Tip #1: One of the most effective ways to improve reading skills is by READING OFTEN!
Studies have shown that by simply reading for 15 minutes a day, students can greatly improve their reading abilities.
Tip #2:
Be an ACTIVE READER! Taking notes and taking multiple pauses while reading is crucial to allow time for your brain to process the new information being acquired. However, refrain from highlighting the entire text by marking only key words.
Here is a general Study Guide for Physics 4A students to learn concepts, reinforce equations, and practice a kinematic problem! Come to the learning center to get help on anything!
