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).

__Distance:__

**Starting from rest**

ΔD=.5AΔT^{2}

**With initial velocity**

ΔD=V_{i}ΔT + .5AΔT^{2}

__Velocity:__

**Starting from rest**

V_{f}=AΔT

V_{f}^{2}=2AΔD

**With initial velocity**

V_{f}=V_{i} + AΔT

V_{f}^{2}=V_{i}^{2} + 2AΔD

__Acceleration:__

A=D/T

__Legend:__

**V**_{f}stands 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.}
