Experiment - Lab Report Example

Introduction

This lab experiment was designed with the major objective of determining whether there is a direct relationship between its position and its average velocity in relation to time. In order to achieve the above objective, the experiment made use of a position-time graph and a velocity-time graph. In this case, the slope of the position time graph was compared against the average velocity obtained from the velocity time graph.

Discussion

From the results attached, the slopes found in the position versus time graphs are reasonably close to the average velocities by only a few percent. Further, when carrying out the consistent, repeatable measurements the slopes of position versus time graph and the average velocity were found to be relatively the same as deduced from the ranges of each measurement. In this case, the maximum value for slope coincided with that for average velocity same as the minimum value; hence, we deduced that the ranges are in agreement. This shows that a change in position against time directly affects the average velocity of the object in question.

Further, the experiment also showed that the relationship between position versus time and velocity is affected by the direction of motion. This was deduced when the motion detector was rotated thereby giving different curves at each instance of rotation. Further, when the graphs for velocity were recorded for the different curves, aforementioned, the velocity versus time graph effectively changed. The rotation of the car leads to a change from a positive slope to a negative slope.  Consequently, this shows that just the way rotation affects the position time graph so it does to the velocity.

In conclusion, the experiment proved that for a moving object, there is a direct relationship between its position and its average velocity in relation to time. 

A possible source of error

The uncertainties arising were attributed to experimental errors arising when taking the readings.
