1. Describing Motion

2. Picturing Motion
Motion Diagrams
A series of images of a moving object

3. Particle Model Particle Model Replacing an object by a single point.
Example  Ticker Timer Lab

4. Vectors and Scalars
A quantity that has only magnitude is referred to as a scalar quantity
A quantity that has magnitude and direction is referred to as a vector quantity
The arrow head indicates direction, while the length of the arrow indicates magnitude

5. Vector Diagrams Interpret the motion of the following diagram.
What would a gradually increasing velocity vector look like? Draw it.

6. Time Intervals and Displacement
Displacement is the change in position of an object (defines the distance and direction between two positions)
Therefore d =df - di
Time interval is the difference between ti and tf
Therefore t =tf – ti

7. Velocity and Acceleration
Average Velocity
Simply the slope of a Position vs. Time Graph
V = d / t = (df – di) / (tf – ti)
Average Acceleration
Simply the slope of a Velocity vs. Time Graph
a= v / t = (vf – vi) / (tf – ti)
