Investigating motion using video processing software Essay

We switched on the laptop and connected the web cam into the USB. Once this was done we make sure that the web cam was working correctly and as soon as this watched checked we began to set up the practical come out of the experiment. We thereforece press record on the web cam employ the software VISILOG and recorded the thumping being thrown in the air next to a good ruler (one metre). Once this had been done we stopped the recording and the replayed the video and one era we were happy, using the software, we recorded the position of the wrap frame by frame.on a lower floor are the results for the first part of the experiment Results Time (s) Height (m) secureness (m/s) Acceleration (m/s2) We evoke then draw a chart using the results and the first represent I have drawn (graph one) is of height of crush puffiness against time taken. Therefore, as we cease get out from the graph if a tangent is drawn we can calculate the incline. The gradient of both sides of the parabola graph is shown on graph one.From the graph we can that as the squash globe is thrown the height of it increases as time increases and as it reaches its peak the ball fastness is expected to decrease due to forces performing on (gravity) and thereof the ball drops down again. The gradient of the graph also calculates the speed (which can be seen of the graph) of the ball because of the conventionality Distance = Speed  Time thusly Speed = Distance / Time From these results a second graph of speed against time can also be make, which is graph two. Again from this graph we can draw tangents and then work out the gradient.Using the gradient we can also work out the acceleration due to the formula Acceleration = change in speed / change in time Therefore acceleration = gradient. Part Two Method We used the homogeneous equipment for the second stage of the experiment only if instead of recording the ball thrown in the air we recorded it as a projectile. To invoice the displacement reaction we used metre rules to measure horizontally as hygienic as unslopedly. Below are the results from the experiment Results take to next page From this table we can draw out a lot of training and from this I have produced a graph of horizontal displacement and vertical displacement (graph three).From the graph we can see that as horizontal displacement increases so does vertical displacement until its peak of 0. 34 m. once the squash ball reaches this height it begins to fall back down due forces acting on it. After the vertical height reaches its peak it starts to decrease but the horizontal displacement continues to increase. From the graph we can also calculate the gradient, which I have done and this can be seen on the graph. Part trinity Method We got a step ladder and to the top of it we attached a wooden beam to it using clamps.Then we got three springs and attached them unneurotic and once this was done we attached the springs to the wooden beam using string. We then added a mass to the springs and recorded the oscillations it did using the camera. Below are the results for this Results See next page From the results (which is a rather long set of data) we can produce a graph and this graph is a sine jolt. inwardly the wave, it can be seen that just about 4 oscillations have been made by the spring. The time taken for 1 oscillation is called the period T. In this case the period T for 1 oscillation is about 1. 31 seconds as shown on the graph.The number of oscillations per unit time is the frequency, f = 1 / T. Therefore, using the formula we can calculate the frequency of one oscillation, which is f = 1 / T f = 1 / 1. 31 f = 0. 763358778 f = 0. 76 Hz Further more(prenominal) as the weights on the spring playact about on a fixed point it means that the wave can be described as a single accordant motion and the acceleration is proportional to its displacement (see graph four for more details) Conclusion Therefore, in con clusion I have shown many things in this three part experiment. For each part, I have produced graphs and shown the results table that I have analysed as well.For the first part of the experiment we can see that from the graphs the squash balls speed increases as it let go from the hand and then as it reaches its peak it begins to lose its speed and comes down, which is also due to forces acting upon the graph. Part two of the experiment is similar in respects and the inequality is that it was a projectile instead. And the third part shows the spring oscillating from a ladder when a weight is attached to it. For more on these carriage at the graphs I have produced and the analysis beneath each part of the experiment.
