  velocity
• Analyze speed graphs

Motion- the objects change in position relative
to a reference point
I. Observing motion (it must have a reference
point/stationary object)
A. Direction and distance (the total
path traveled) B. Displacement- change in
position of an object 1. Must be a
straight line (Usually shorter
than distance) 2. Must include a direction
4
II. Speed and Velocity A. Speed is distance
divided by time (when motion
occurs) 1. SI unit is m/s 2. Constant speed
is speed that does not change
B. Speed can be determined by a
distance-time graph
5
C. Average Speed- distance/time D.
Instantaneous speed- over a very small
amount of time, what it is traveling
at that point
E. Velocity 1. Speed plus a direction 2.
Resultant Velocity- a combination of
velocities added together
