Motion Terms

Time (t):

Time is measured in seconds (s).

The values in this column represent the elapsed time from the start of the motion.
Position (Position):

Position is measured in centimeters (cm).

Taking towards left as positive, it represents the displacement of the object from its initial position at each given time.
Distance per second (Dist per second):

This column represents the distance covered by the object in each second.

If the values are constant at 50.0 cm, indicating that the object is covering a consistent distance of 50 centimeters in each second.
Speed (Instantaneous Speed):

Instantaneous Speed is the rate of change of position at that time.

If the acceleration is zero, the instantaneous speed at t = 4 for example, is (200-150)/(4.00-3.00) = 50.0 cm/s
Average Speed (Average Speed):

Average speed is the total distance traveled divided by the total time taken.

If the total distance over is 300.0 cm and the total time taken is 6.00 s, the average speed is 300/6.00 = 50.0 cm/s.
