Step 6

3. Gravity and Kinetic Energy Course, 1.2: Acceleration Track
Fill in data tables

Step 7

4. Gravity and Kinetic Energy Course, 1.2: Acceleration Track
Observe track speed
Change of speed (Δv) during each second
Acceleration (a) during each second

Step 8

5. Gravity and Kinetic Energy Course, 1.2: Acceleration Track
Observe track speed
Did you try to travel at a constant speed when you moved down track B?
Did you try to travel at a constant speed when you moved down track C?
How could you calculate how much the speed changed (Δv) from second to second?

8. Gravity and Kinetic Energy Course, 1.2: Acceleration Track
Complete data table
What was the change in speed for each second for track B?
What does it mean that for track B, there was no change in speed?
What was the change in speed for each second for track C?
What does it mean that for track C, there was a change in speed of 0.5 m/s for each second?

9. Gravity and Kinetic Energy Course, 1.2: Acceleration Track
Discuss slope
What does the slope of a graph line tell us about speed?
But if you look at the way the line curves between each point as time increases, what do you notice about the shape of the graph for track C?
