Russell Hochman Partner: Alisha Mayer Lab Section 7 1/31/11 Lab Report 2: The acceleration due to gravity Abstract: This experiment is designed to find the acceleration due to gravity on the earth using a weight, wax paper, a standee and a voltage box. We will be computing the acceleration of the weight by dividing the distance travelled in .0167s (6 dots from the initial dot) by .0167s to find the velocity and then to find the acceleration due to gravity we need to plot the velocity versus time graph which we found to be 9.79 ±.07920 m/s². in order to do this we needed to plot the points and add a best fit line to find the acceleration. Question 1) Displacement, (x), is the area under the graph of velocity versus time which is the total distance the objected travelled. Average velocity, ( = = - - vinst ∆x∆t xf xitf ti ) , is the change in distance over change in time. Instantaneous velocity, ( = ) vavg dxdt , is the derivative of data over derivative of time. Acceleration, ( = = = - ) a ∆v∆t dvdt ∆x∆t ∆t , is the slope of the velocity and time graph.
