  1. Today we got into our lab groups and recorded our data on the graph on the computer. Then, we calculated our number to find the difference between the times. After finding out the difference, we figured out what happened between times. If the time decreases between interval one and two, then the car is getting faster. When a distance versus time graph curves, the speed of your object is changing. Now looking between intervals two and three, the car slowed down slightly. Calculate the speed at each timing point?
    trial 1
    trial 2
    trial 3
    What can you tell me about the speed from
    trial 1
    trial 2
    trial 3
    Draw three more graphs each has TIME in Seconds as the x axis and SPEED in yards per second as the Y axis.
    Due Monday!

    Trial 3- 13.9,14.3,17.4,18.9

    2.
    Trial 1- Started fast then slowed down in speed.

    Trial 2- The speed increased through interval 4.

    Trial 3- The speed increased.

    Trial One:The speed decreases from intervals1-3 and increased and slowed on the 4th interval.

    Trial Two:The speed increased in intervals 1-2 and stayed almost constant from 2-4.

    Trial Three:The speed increased from intervals 1-3 and decreased slightly from 3-4.

    Trial Two:
