1. Unit 1 Notes

2. 3 Step Solutions 1)Write the general equation (and rearrange as necessary). 2)Plug in numbers. 3)Solve.

3. Motion Maps For position, the end of the arrow shows position at the beginning of a time interval. The length of the arrow shows velocity (change in position during the time interval). A dot indicates no movement during a time interval

4. Example Motion Map t(s)x(m) 00 12 24 37 47 53

5. Definitions Qualitative: not using numbers. – Just the right general idea (positive/negative, increasing/decreasing) Quantitative: Using Numbers – Both the general idea and the numbers have to be correct

6. V vs T Motion Map In a velocity motion map, the end of the arrow or the dot shows the velocity at the beginning of a time interval. The length of the arrow shows the change in velocity during that time period (acceleration).

7. Note that the velocity is the change in the length of the arrows from the position motion map.

8. A vs T Motion Map A dot/tail end of an arrow shows the acceleration at the beginning of a time period. Since we only deal with uniform acceleration, these should be dots stacked at some number for acceleration at every time.
