1. Motion
Investigate the relationships among speed, position, time, velocity, and acceleration.

2. Distance Frame of reference Relative motion Distance
System of objects that are not moving with respect to each other
Relative motion
Movement in relation to a frame of reference
Distance
Length between two points

3. Displacement Displacement Vector Adding vectors Resultant vector
The direction and length
3 meters west of the door
Vector
Magnitude and direction
8 feet left
Adding vectors
If on the same line, just add or subtract the magnitudes
Resultant vector
If in various directions, the vector is the displacement from beginning to end

4. Speed Distance an object moves compared to the time it takes to move
SI unit meters per second m/s
Average speed
The total distance divided by total time
Instantaneous speed, n
The speed at that specific moment in time

5. Graphing Motion Distance on the y-axis Time on the x-axis
Slope is the speed
Horizontal lines mean object has stopped

6. Velocity Speed and direction Combining velocities 80 mph east
Add by vector addiction

7. Acceleration Change in speed, direction, or both
Change in speed, direction, or both
Positive acceleration is speeding up
Negative acceleration is slowing down
Constant acceleration is a steady change in velocity
Acceleration is change in velocity over time

8. Graphing Acceleration
Velocity on y-axis
Time on x-axis
Slope is acceleration
Horizontal line means no change in acceleration
