![]() ![]() You also see above that the vertical velocity at the maximum height is zero. As it starts to fall again after reaching maximum height it starts to speed up as gravity becomes stronger when you get closer to the certain of the earth. The vertical velocity is slowing down as it reaches its maximum height due to gravity. The horizontal velocity stays the same throughout, meaning that there is no horizontal acceleration as there are no left or right forces acting on the object (Gibbs, 2013). This means that the acceleration of the frisbee is 9.8m/s^2. When an object is following a projectile pathway, only one force is acting on it and that is gravity. Therefore when wanting to through the frisbee at a higher maximum height you must increase the angle you throw the frisbee at. Where as a person that was 1.5240m would have to reach or jump to try and interfere with the frisbees pathway. If you threw a frisbee at an angle of 30 degrees, and if they were standing right where the frisbee reached the maximum height they would be able to get it. ![]() For example if a person that was 1.8288m was guarding you, verses someone that was 1.5240m. ![]() It is important for a frisbee player to understand how maximum height works and affects frisbees as in order to pass over a person with a tall reach they must understand that they need to throw it at a greater angle as it needs to reach a higher maximum height then throwing it over a person who is shorter. By doing this it allowed me to find the proper maximum height which was 1.6036m. Therefore once collecting all of these numbers, I used one of the 'BIG FIVE' equations to calculate by maximum height. I knew from collecting my data that the frisbee had travelled 10.6m (which was measured by a meter stick) and that the time the frisbee was in the air was 1.66s (which was measured by a stopwatch). The frisbee starts at a higher height then it finishes at so, to find the maximum height I needed to make sure I added the starting height from the height at the top of the projectile. I was able to find the maximum height after I calculated the horizontal velocity, vertical velocity and the resultant velocity by using equations I had learned in class. As you can see from the picture the frisbee is not much higher than his head, so the angle degree he threw the frisbee at could not of been very large. This means that the maximum height of the throw is in the middle of the pathway. These numbers make sense as the throw is a projectile. ![]()
