Being in my second year of advanced placement physics, I have had all of last year in physics to establish a fair grasp on the equations for velocity, position, and acceleration. There are basically two types of equations (velocity & distance) that are used when solving for velocity, position and/or acceleration. These two types of equations have two forms (when the object is at rest & when it is already moving).

Starting from rest
With initial velocity
ΔD=ViΔT + .5AΔT2

Starting from rest
With initial velocity
Vf=Vi + AΔT
Vf2=Vi2 + 2AΔD

Vfstands for final velocity. (the velocity reached after so much time has passed)
A is the objects acceleration
D represents distance or displacement
T is the amount of time in question
Δ Delta stands for "change of". The Greek letter (delta) designates a change in the quantity of the variables D and T

  Now that you have all the equations and know when to use each one, go solve some problems and impress your friends by telling them how fast a penny is traveling when dropped from the Sears Tower (or some other very tall structure)

Disclaimer: These equations will only give you an idea of the distance, velocity or acceleration of a object in real life. The only time when these equations work perfectly is in Utopian Physics.
