A video that we made that accurately represents acceleration was to have someone start at a stand still, then sprint forward as fast as they could. This shows acceleration because as the runner moves across the floor they pick up speed until they are out of frame. Our graph showed acceleration with a curved slope and showed a constant acceleration of 4.2 meters per seconds. We are out to show how acceleration takes place in real world situations. Future plans for this topic could be to film a car accelerating from a dead stop and figuring out the acceleration of the car.
This week we made a video on acceleration or speed up, slow down, or change in direction. We made a video to show acceleration by Connor running a sprint. This started by him in a rest state to a all out sprint state. Durning the time he went full sprint shows acceleration because he has to gain speed to move faster and faster. After this we used Logger pro to analyses the video. This showed, in fact, it was constant motion because the 1st graph we used showed velocity which shows his increase in speed over seconds. We found the exact slope which was 4.2 m/s. This week has been very productive and i learned a lot more on acceleration especially that it can be a change in direction as well.
We have two videos that we took. The first video is of Connor on the starting blocks in real time. The next is of Connor again, but in this one is in slow motion. We focus on the the start of his acceleration to watch he gets out of the blocks. The start of a race in the most important part of the race. The person that can accelerate the fastest out of the block usually win the race. The next two pictures are the Loger-Pro data results in a graph. The first graph is a velocity graph. Although it is a bit scattered around we still can make out the increase of speed Connor makes every second. On average he increase by a velocity of 4.2 mps. The next graph is a graph that the increase in slope. The increase in slope shows the increase in speed that Connor makes with every second that passes.
This week we studied constant motion. Constant motion is when a object moves at a constant speed. We decided to use a basketball rolling across the floor for this because it was very easy way to show constant motion and was a good introduction to all the different tools used to create the video and page. Our video, for example showed constant motion because our graph moved downed diagonal. This also is backed up by the slope which showed consistent dots moving down. Other sports that represents this are Nascar, passing a hockey puck across the ice. Next week, i hope we can continue good work and find new ideas to show acceleration, which is our next unit.
To find constant motion being used in a real life situation, we made a video showing a ball rolling by at a constant speed. The ball rolled by at a constant speed, which was displayed on the graph because, on the graph the points plotted resembled a straight line. We made this video to gain a better understanding on how constant motion looks and works. Future plans on how to display constant motion could be to film a hockey player passing a puck along freshly zambonied ice and observe the constant speed.
Constant motion is the when an object moves the same speed during the duration of the video. When we rolled a ball across the floor of the gym, the ball did not go up in the air or drop so the graph is a straight line. The graph is a diagonal line because in order to tell that the ball is staying at a constant speed the slope need to be the same. A consistent slope throughout the graph means a consistent speed throughout the graph. We see this type of motion in a couple sports. One of them is would be when one hockey player passes the puck to another as long as the puck does not leave the ice. The next is curling,
