Acceleration due to gravity Lab Report 2Abstract:This report summarizes the procedure, execution, and results of an experiment conducted atthe University of Arizona’s PHY141 lab to find the acceleration due to gravity. Tosuccessfully conduct this experiment a PASCO wireless smart cart and a track were used andthe acceleration of the cart due to gravity was calculated. The PASCO wireless smart cart andtrack allowed us to manipulate the heights and angles of the track to obtain various sets ofdata from multiple trials. From the data collected over five different heights with five trailseach, the average calculation for the acceleration due to gravity is 10.1 m/s2.Introduction:In this lab, we are calculating the acceleration of a wireless PASCO cart due to the gravity ofthe earth. We used a 120 cm track and elevated one of its sides to different heights to createan unknown angle . The cart is then placed at the highest point on the track, and theacceleration of the cart as a function of time is calculated by the PASCO capstone software.The same software is then used to find the mean acceleration of the cart. The acceleration dueto gravity can be found by using the equations for Newton’s Second Law and the cart’sacceleration y-component. Then a graph is drawn of average acceleration vs height and itsslope is used to find the acceleration due to gravity. Theory and Derivations:
Acceleration due to gravity Lab Report 3When the cart is elevated to a certain height ‘h’, it forms an angle ‘’ with the horizontalplane. The length of the race track used for this experiment was around 119 cm but to get theequation, lets assume its ‘L’. CartlhThe force experienced by the cart is F=m.a, where m is the mass of the cart and a is the acceleration. Which can be resolved into mg sin where is the angle between the track and the horizontal.
