2. Compare the difference between speed and velocity Analyze speed graphs
Objectives
Compare the difference between speed and velocity
Analyze speed graphs

3. Motion- the object’s 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. A. Speed is distance divided by time (when motion occurs)
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
Distance
Time

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
