5. What is Acceleration?
The rate of change of velocity with respect to time.
aavg = Change in velocity
time required for change

9. Guided Practice
Page 12 of Scientific Notebook
A car accelerates uniformly from rest to a speed of 6.6 m/s in 6.5 s. Find the distance the car travels during this time.
21m

10. Guided Practice
Page 12 of Scientific Notebook
A driver in a car traveling at a speed of 21.8 m/s sees a cat 101 m away on the road. How long will it take for the car to accelerate uniformly to a stop in exactly 99m?
9.1 s

11. Independent Practice
Turn in to Teacher
A car enters the freeway with a speed of 6.4m/s and accelerates uniformly for 3.2 km in 3.5 minutes. How fast (in m/s) is the car moving after this time?
24m/s

13. Closure: Did you Know?
Decreases in speed are sometimes called decelerations. Despite the sound of the name, decelerations are really a special case of acceleration in which the magnitude of the velocity – and thus the speed - decreases with time.
