1. Section 1.3 Acceleration measures how fast velocity changes.
Mrs. Leos

3. Acceleration: the rate with which velocity changes over time.
If velocity does not change, there is no acceleration

4. Changing Acceleration
Speeding up
Slowing down
Changing directions at a constant speed
Changing directions while slowing down or speeding up

5. Vectors To explain VELOCITY Show size and direction

6. Vectors To explain ACCELERATION Show size and direction

7. Vector To show acceleration Called negative acceleration rs

8. Vectors to show acceleration Change in direction

9. Investigation: Acceleration
MOVEMENT OF STRING
ANSWER: WHAT DO YOU THINK QUESTIONS
While speeding up
While slowing down
While walking steadily

10. Acceleration can be calculated from velocity and time
The change in velocity can be found by comparing the initial velocity and the final velocity of the moving object.
I. .Acceleration can be calculated from velocity and time

11. Formula for acceleration

12. Units for acceleration
Units for a = m/s2

13. Calculating Acceleration
WRITE OUT Sample Problem

14. MATH PRACTICE PROBLEMS

15. Velocity-Time Graphs
Velocity- time graphs are used to understand acceleration
Draw Velocity-Time graph on page 30 (textbook)

16. On the left side of notebook demonstrate your understanding of Section 1.3
Thinking map, rap, comic strip, foldable
Write your summary
