6. Speed Change in __________ ____________________
Average speed - most common measurement
Instantaneous speed - ____________________________________

7. Example: average speed
Calculate average speed between trip times of 1 h and 3 h

8. Velocity
Describes __________ (How fast is it going?) and ______________________ (Where is it going?)
Graphical representation of vectors: ___________
__________________________________________

9. Acceleration
Rate at which motion changes over time
Can be negative

10. Uniform Acceleration Constant, _______________________________
Average velocity simply related to initial and final velocities in this case
