2. Daily Reflection
Prompt: What is the formula for calculating velocity?

3. What is the formula for calculating speed?

4. Which Speed is fastest? 5
300 2
1000

5. Which Speed is fastest?
5 km
300 cm
2 km
1000 m

6. Which Speed is fastest? 5 km / hr 300 cm / hr 2 km / sec 1000 m / hr
2 km/sec is the fastest
We need both the distance and time unit of measurement to determine speed

7. What is average speed?
The total traveled divided by the total time elapsed.
The speed of an object along the path traveled can vary

8. What is difference between velocity and speed?
Velocity: Speed of the object and direction of motion
Speed: Just the speed. We don’t know the direction of motion

9. A car was traveling north at 50 km/hr
A car was traveling north at 50 km/hr. It started to travel northwest at 50 km/hr. Did the speed change? Did the velocity change?
Speed did not change
Velocity changed

10. What is slope of a line? The steepness, or slant, of a line on a graph
Slope tells you the rate of change.
What is the slope of the graph?
10 m/s

11. How much did the jogger travel after 1 minute?
About 200 Meters

12. How much did the jogger travel after 5 minutes?
About 800 Meters

13. How much did the jogger travel after 8 minutes?
About 800 Meters

14. Did the jogger move between the 5 minute and 8 minute mark?
No. The jogger was at rest

15. Calculating Slope Rise over Run

16. What is Acceleration? Rate at which velocity changes Increase in speed
Decrease in speed
Change in direction

17. What are some examples of objects continuously changing direction?
Ferris Wheel
Moon
Earth

18. If a car keeps a steady speed of 100 km/hr on the highway but changes directions slightly, is it accelerating?
Yes

19. What is the formula for calculating acceleration?
