 Avg speed

Rate at which distance is covered over time
How fast you are going, not where  Instanteous Speed
 How fats one is going at a given instant (choose very small interval)
 Velocity

Direction of motion and how fast
Has magnitude (sizefast) and direction  Vector

A quantity that has both magnitude and direction
Length of arrow=vector quantity
arrow=direction  Vector Quantity

Any quantity for which both size and direction are needed for a complete description
IE:velocity, acceleration, force, moment  Instanteous Velocity

Vector Quantity.
Size equal to instanteous speed and the direction that corresponds to the object's motion  Acceleration
 The rate at which velocity changes
 Avg. Acceleration
 Change in velocity over the time to make that change
 Instanteous accelration
 Rate at which velocity is changing at a given instant of time
 Uniform Accelratijon
 Acceleration that does not change as motion proceeds
 Slope of a PvT graph
 Velocity
 Slope of a VvT graph
 Acceleration
 Slope of a Unifrom Acceleration Graph
 Horizontal Line
 Slope of a Distance v Time curve
 Instanteous/velocity
 Slope of DvT:Large upward slope:
 Large instanteous velocity
 Slope of DvT=constant
 velcoity=constant
 Steep slope of VvT=
 Rapid change in V, large acceleration
 Horizontal line for slope of VvT
 Zero Acceleration
 Uniform Acceleration in a VvT
 Constant slope (upward if positive, vice versa)
 Area under an Acceleration v T
 Change in Velocity
 Area aunder a VvT graph
 Change in posititon/distance traveled?
 Eqn for Avg Speed

Distance traveld/time of travel
s=d/t  Eqn for avg. Acceleration

Change in V/elapsed time
a=change in v/t  Eqn for distance

Velocity times time(with constant v)
x=vt  Getting V from a Uniform Acceleration Grpah

V at any time=original v +velcoity fained.
Velocity is gained b/c of acceleration
Change in V=at
V=Vo+at  Finding D in V graph with nonconstant V and initial v=0

x=(.5)at^2
t goe sin twice to find avg v and to find distance  Avg velocity (if start is 0)
 1/2 final v
 final V
 at
 Finding D in V graph with motion before acceleration

D=VoT+(.5)at^2
same equation just accounts for intial velocity times time (distance it moves with contant v)
sum of rectange and trainfe  finding a in an AvT graph
 A=constnat
 Avg V

Total change in psotition/elapsed time
delta x (with vector)/delta t  Finding position from a velocity v time graph
 x=(.5)AT^2+VoT+Xo
