Gravity and Kinetic Energy Course, 1.2: Acceleration Track Focus question What is acceleration? Gravity and Kinetic Energy Course, 1.2: Acceleration Track Step 6

Gravity and Kinetic Energy Course, 1.2: Acceleration Track Fill in data tables Change in time (Δt) Change in position (Δx) each second Average speed (v) during each second Gravity and Kinetic Energy Course, 1.2: Acceleration Track Step 7

Gravity and Kinetic Energy Course, 1.2: Acceleration Track Observe track speed Change of speed (Δv) during each second Acceleration (a) during each second Gravity and Kinetic Energy Course, 1.2: Acceleration Track Step 8

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? Gravity and Kinetic Energy Course, 1.2: Acceleration Track Step 8

Gravity and Kinetic Energy Course, 1.2: Acceleration Track Complete data table Calculate the change in speed during each second for track B and track C. Gravity and Kinetic Energy Course, 1.2: Acceleration Track Step 9

Gravity and Kinetic Energy Course, 1.2: Acceleration Track Complete data table Gravity and Kinetic Energy Course, 1.2: Acceleration Track Step 9

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? Gravity and Kinetic Energy Course, 1.2: Acceleration Track Step 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?
