The five steps to solving a physics question
confidence, diagram, system, formula, plug n chug

This is a physical quantity that has magnitude but no direction
scalar

this has a physical quantity with both magnitude and direction. Can be represented by an arrow
A vector

A^{2} + B^{2} = C^{2}
Pythagorean Theorem

What does SOH CAH TOA stand for?
 Sine Opposite over hypotenuse
 Cosine adjacent over hypotenuse
 Tangent opposite over adjacent

Any vector can be replaced by this type of vector. They are always at right angles to each other and their sum is equal to the vector being replaced.
Component Vector

The most common triangle for the MCAT

scalar: Distance/time =
vector: displacement/time=

This vector is defined as the rate of change in velocity either in magnitude or direction.
Change in velocity/time
acceleration

uniformly accelerated motion is motion with constant acceleration.
What are the three uniformly accelerated motion?
 x=x_{0}+v_{o}t+(1/2)at^{2}
 v=v_{o}+at
 v^{2}=v_{o}^{2}+2ax

what is the equation for average veolcity?
v_{avg}=(v+v_{o})/2

The peak height for the projectile formula
v_{o}sin(teta)=square root(2gh)

A large one of these increases air resistance because it allows for more collisions with air molecules
surface area

This is created when projectile collides with air molecules. It is a type of friction that is affected by surface area, shape, and velocity. Mass doesn't change it but it can alter the path of the projectile.
Air resistance


formula for velocity
velocity = displacement/time

formula for acceleration
acceleration=change in velocity/time

another formula with constant acceleration
v= square root(2gh)
what is the value of g?
g= 10m/s^{2}
