Studying Changes in Speed and Velocity Through Graphs: Weekly Blog #13

The matching I did with my group

Summary:

This week in science, I learned a lot about how graphs can represent data and replicating a certain situation. This, of course, is directly correlated to the distance that an object takes in a certain amount of time. Speed is a scalar quantity that represents how fast an object is moving. Velocity is a vector quantity that measure how fast an object is moving, and the direction its moving in. There are several different scenarios that we looked through as a group, and we had to figure out which scenario corresponded best with the graph. Through this, I was able to learn what it means  to speed up, or slow down  by looking at the data, and then being able to understand what that would visually look like on a graph. In order to figure out how fast an object is moving, you have to calculate how the object has changed in response to how much distance(rise) an object has take over the time(run).

S&EP - Analyzing Data

I had to analyze the data given to us in the different scenarios that were corresponding with the speeds that Joe was going at. Through all these different situations, we had to dissect all of elements that went into each story, and attempt to most closely relate it to one of the given graphs. Later on, we also had to see how the graphs numbers changed in relation to his time and distance by plotting down his distance at certain times. This proves that this week, I went through a deep analysis of data in order to relate all the information. 

XCC - Patterns

I started to notice patterns that would occur when Joe went through different situations that were somewhat similar to each other. This could be seen when Joe experience a situation where he went faster, I noticed that the start and end of the line was tighter. This could also be seen when he went slower, the lines were more extended. Some other patterns i noticed were every time he didst move, the line was strait, but didn't change in distance, just increasing in time. Also, when it said that Joe was coming back to his origin, you always see that the line comes back to the bottom of the graph or at 0 distance.
