Movement of Balls at Acceleration - Lab Report Example

Physics Lab Report Task: To determine whether a ball rolls down a decline at a constant acceleration IntroductionIn this experiment, members used balls on inclined rumps and tried to see whether there was any dependence on the acceleration and thereafter calculate the experimental acceleration comparing it with the theoretical acceleration. Given that the theoretical slope = ½ ax and the theoretical acceleration was ax = 1.12 m/s2. Thus, the experimental acceleration at a distance of 3 meters = (1/2)a (2.24)2 where a=1.

20 m/s2 (That is Xf= (1/2) ax t2)Solving for the final velocity: this was given by Xf= 0 + ½(0 + Vfx) t, Vfx = 2 Xf /t Thus the final velocity = 2(3m)/2.245 = 2.68: The experimental equation was given by Xf = 0.5614 t2 + 2.56ProcedureChose a ramp and measure out 3 meters using 2- 12 inches rules then roll a ball at the apex of the ramp, making sure that the seams are placed in the same direction as the trial before-time (in this case we use our phones) at each incremental for 6 trials. Thereafter, we plotted time(s^2) against time.

A straight line was produced. According to the discussion theoretical acceleration was given by multiplying the theoretical slope by time.DataAverage Time(s^2)Distance1.27^2=1.611 m1.64^2=2.692 m2.24^2=5.023 mGraphDiscussion of ResultAs discussed earlier, the theoretical acceleration obtained was 1.12 m/s2 while the experimental acceleration was given as 1.20 m/s2. The variation in the acceleration was caused by slight errors that were experienced during the experiment. However, since the margin error was +/- 0.

1 m/s^2, indicates that the predicted acceleration and the experimental acceleration are equal.
