All the velocities are divisible by three because Vavg= total distance fall in each time interval/time elaspedelapsed. For example, 3/60sec equals to 0.5sec. This indicates each 60 sec, time intervals increase at acceleration.

DrawDrawing the line on the graph by connecting two dots from first to last may be easy if we have athe right calculation. This experiment is varyvaries due to gravity and acceleration. We need to measure carefully and calculate with formulas to find the answers.

The best-fitbest fit line does not go through the origin because we start t1=3/60 as our first point from the starting point. We don't need to use zero because it may result thein a small number or an error. Y- intercept represents total distance fallen(cm).
