Acceleration due to gravity Lab Report 1 Acceleration Due to Gravity Lab Report UTKARSH UPADHYAY ( BAAP HU TERA ) PHY141 Tenzin Phakdon Due Date: 02/09/2021
Acceleration due to gravity Lab Report 2 Abstract: This report summarizes the procedure, execution, and results of an experiment conducted at the University of Arizona’s PHY141 lab to find the acceleration due to gravity. To successfully conduct this experiment a PASCO wireless smart cart and a track were used and the acceleration of the cart due to gravity was calculated. The PASCO wireless smart cart and track allowed us to manipulate the heights and angles of the track to obtain various sets of data from multiple trials. From the data collected over five different heights with five trails each, the average calculation for the acceleration due to gravity is 10.1 m/s 2 . Introduction: In this lab, we are calculating the acceleration of a wireless PASCO cart due to the gravity of the earth. We used a 120 cm track and elevated one of its sides to different heights to create an unknown angle . The cart is then placed at the highest point on the track, and the acceleration 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 due to gravity can be found by using the equations for Newton’s Second Law and the cart’s acceleration y-component. Then a graph is drawn of average acceleration vs height and its slope is used to find the acceleration due to gravity. Theory and Derivations:
Acceleration due to gravity Lab Report 3 When the cart is elevated to a certain height ‘h’, it forms an angle ‘ ’ with the horizontal plane. The length of the race track used for this experiment was around 119 cm but to get the equation, lets assume its ‘L’. Cart l h The 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.
