3. Acceleration (Right) W. is acceleration? How do you calculate acc.?
W. is the unit for acc.?
W. is the relationship btw force/mass/and acc.?
Acc.- the change in velocity over time (speed up, slow down, change direction)
2) a = (sf-si)/t
If the number is negative you are slowing down***
3) m/s2 (meters per second per second). How velocity (m/s) changes over time (s)
4) F= m *a
m = F/a a = f/m

4. BRAIN [POP] Please watch the video through 1 time WITHOUT WRITING.
We will watch two more times and then fill out the notes

6. 1. a = (sf-si)/t sf = 10m/s si=2m/s t= 2s Calculate acceleration 2
1. a = (sf-si)/t sf = 10m/s si=2m/s t= 2s Calculate acceleration a = (sf-si)/t sf = 20m/s si=4m/s t= 8s Calculate acceleration

7. LAB
Where our data could have been damaged…

8. Exit slip The formula for speed = time/distance True b. false
2. Velocity is distance and direction
3. Acceleration is how speed changes over time
a. True b. false
4. Distance = 10m time = 10s Calculate speed
5. a = (sf-si)/t sf = 10m/s si=4m/s t= 2s
Calculate acceleration
*** MUST USE CORRECT UNITS
