Post-Lab 1 Assignment: Introduction to Measurement and Uncertainty In Lab 1, the average speed of a cart on a ramp was calculated by measuring the distance of the track and timing how long it took for the cart to hit the end of the track. Once these values were determined, the equation for average speed was utilized to find the carts average speed down the track. Since there is uncertainty with every measurement, we used the equation for uncertainty to calculate the uncertainty within our measurements. We concluded the average speed of the cart was 84.0 ± 0.8 cm/s. There is confidence in our measurement of average speed since we accounted for uncertainty. Therefore, our speed could vary by 0.8 cm/s and still be accurate. To account for this uncertainty accurately, the uncertainties of both the distance of the track and the time it took for the cart to travel to the end of the ramp had to be considered in the final uncertainty equation.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
