To find average velocity I did the following: One example calculation would be at 0.2 seconds, when displacement is 9.2cm. Position from the start (cm)Īverage velocity was found by dividing change in time by displacement. I measured and recorded the position from the start of the tape corresponding to each half time interval and then plotted a velocity-position graph using the velocities I recorded. I calculated the slope of the velocity-time graph, which gave me acceleration in cm/s^2. I plotted a graph of velocity against time using the half time intervals. I calculated and recorded average velocity for each 6 dot interval. I measured and recorded the displacements corresponding to the 6 dot intervals in table 1. Afterwards, individually we analyzed the tape which had been marked into 6 dot intervals. We started the timer and then released the 50g mass.
We threaded the recording tape through the timer and held the upper end vertical to minimize the friction between the timer and the tape. We used masking tape to attach a 50g mass to the end of the 121cm recording tape. Me and my lab partners clamped a recording timer in a vertical position above the floor as shown in figure 1. I used the table on the given lab sheet to design a table for my results.
And the velocity-time graph will be a straight line. The acceleration for the object in the velocity-time graph will be gravity (9.81 m/s^2). It is hypothesized that the object that is dropped will endure gradual change acceleration in acceleration. Also, to determine the position from the start of the fall.
#Freefall and acceleration due to gravity lab free
The purpose of this lab was to evaluate the increase in velocity with time during a free fall.
