1. ACCELERATION & GRAPHING MOTION

2. 3 Ways to Accelerate
Speed up
Slow Down
Change Directions

3. True or False
It is not possible to accelerate if you are going constant speed

4. The change in velocity over time.
Acceleration
The change in velocity over time.

5. Solving Acceleration (You do not need to know this)
Mr. Almero is cruising down the street in his Ferrari at a speed of 30kmh. He sees a dog run in the street so he slams on the brakes. In 2 seconds he comes to a complete stop and avoids hitting the dog. What was the rate of acceleration of Mr. Almero’s Ferrari when he slammed on the brakes?

6. Solving Acceleration (You do not need to know this)
Mr. Almero’s Lamborghini can go from 0-60mph in 2.5 seconds. How quick can it accelerate?

8. Rates of Acceleration + Acceleration → Speeding Up
- Acceleration → Slowing Down (Deceleration)

13. Graph the following Speed vs. Time for A, B, C

14. Graphing Motion – Key Points
Position/Distance vs. Time Graphs
Straight lines = constant speed
Slope = rise/run = distance/time = Speed
Steeper slope → Higher Speed
Speed vs. Time Graphs
Flat lines (0 slope) = constant speed
Positive slope = speeding up
Negative slope = slowing down
