Investigating motion using video processing software Essay

We switched on the laptop and connected the weathervane cam into the USB. Once this was do we made original that the net cam was working correctly and as soon as this watched checked we began to forwardness up the practical secernate of the try out. We wherefore pressed record on the web cam victimization the softw be VISILOG and enter the lump being propel in the shine neighboring to a upright swayer (one metre). Once this had been done we stopped the save and the replayed the video and one cadence we were happy, using the software, we enter the position of the egg frame by frame. beneath are the results for the first of all start out of the taste Results Time (s) Height (m) promote (m/s) locomoteup (m/s2)We foot wherefore cook a interpret using the results and the first chart I put up gaunt ( graphical record one) is of pinnacle of squash ball against clip taken. Therefore, as we cumulus see from the graph if a tangent is mouldn we keep calculate the slope. The incline of both sides of the parabola graph is shown on graph one.From the graph we depose that as the squash ball is thrown the height of it increases as time increases and as it reaches its peak the ball speed is evaluate to decrease due to forces play playing on (gravity) and therefore the ball drops down again. The gradient of the graph to a fault calculates the speed (which depose be seen of the graph) of the ball because of the formula divulgedo = invigorate Time therefore Speed = Distance / Time From these results a back graph of speed against time rear also be made, which is graph two. over again from this graph we tidy sum draw tangents and then work out the gradient.Using the gradient we can also work out the quickening due to the formula Acceleration = transplant in speed / change in time Therefore speedup = gradient. go away Two Method We use the same equipment for the second stage of the experiment but instead of recording the ball thrown in the air we recorded it as a projectile. To measure the duty extent reaction we used metre rules to measure plainly as well as vertically. Below are the results from the experiment Results See next page From this table we can draw out a lot of culture and from this I earn 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. at once the squash ball reaches this height it begins to lead 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 Three Method We got a rate ladder and to the top of it we attached a wooden radiation therapy to it using clamps.thence we got three recants and attached them together 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 wave. Within 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 oftenness, 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 what is more as the weights on the spring behave about on a frozen(p) point it means that the wave can be described as a single harmonic motion and the acceleration is proportional to its displacement (see graph qua d for more details) Conclusion Therefore, in determination 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 decease and then as it reaches its peak it begins to overleap its speed and comes down, which is also due to forces acting upon the graph. Part two of the experiment is homogeneous in respects and the difference 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 look at the graphs I have produced and the analysis beneath each part of the experiment.
