12/10/2017 Motion of an Amoeba – ABSTRACT In this lab, I observed the stop motion image of amoeba, figured out a scale factor to measure the position, velocity, and acceleration vs. time data. Since the amoeba doesn’t have rigid shape, I decided to measure its position based on the position of its north most tip. With that strategy in mind, I drew lines parallel to the x axis of position for each motion track. Then, using a ruler, I measure the distance the Amoeba traveled for each track in cm. Finally, using the following formula (scale factor = Scaled length/ original length) I calculated a scale factor and determined that for each 100 micrometer of motion on the paper is equal to 7.4 cm of my ruler measurement yielding a scale factor of 16.2. The rest of the position measurement in cm measurement were converted to micrometer by multiplying the each cm measured position by 16.2. Questions: 1)Upon observation of the velocity graph and with exception of a couple of outlier, its could be hypothesised that the velocity of amoeba is constant throughout most of the track.
