###
motion

a change in position relative to reference point

###
frame of reference

a way to show precise location of object in space, time is:

###
displacement

measures distance between start and end point

###
speed

how fast object moves in a given time

###
v=d/t

what is the formula for average speed?

###
d=vt

what is the formula for distance?

###
t=d/v

what is the formula for time?

###
velocity

what is the speed of an object in a direction called?

###
positive velocity

velocity of an object when it moves toward reference point

###
negative velocity

velocity of an object when is moves away from reference point

###
resultant velocity

addition of positive and negative velocities is called:

###
constant speed

what speed is the speed when distance and time are equal?

###
meters/second

what is the SI unit for speed?

###
distance-time graph

the graph that shows speed of an object

###
speed

what does the slope of a distance-time graph show?

###
fast

if the slope on a distance-time graph is steep is the object travelling fast or slow?

###
Zero Slope

what is the slope of an object thats not moving

###
distance, y axis

what is the independent variable on a distance-time graph and which axis is it on?

###
time, x axis

what is the dependent variable on a distance-time graph and which axis is it on?
