Acceleration is the measure of changes in velocity over time. Any object that is experiencing change in speed and direction is considered to be accelerating. Because of this,acceleration is measured as a vector quantity. This means that it measures both the magnitude and direction of an object. You could also model acceleration by using a graph. in order to graph acceleration, it has to be a velocity vs. time graph. When an object has negative acceleration, it is known as deceleration. When I was able to apply the knowledge of acceleration all throughout the week. This was most notable in this weeks lab.
S&EP - Analyzing Data
This week in science, we did a lab using Hotwheels race cars to examine changes in acceleration. Through this experiment, we were able to collect data while running different tests on the cars, closely examining their speeds at different times. We varied the slopes of the ramps, as well as how long the track was both times. We then had to record all of this data we collected from the different experiments onto our papers. From there, we were able to convert all the information into a few different types of graphs, and we looked to see the similarities between them.
XCC - Stablitity and Change
There is a great example of stability and change that can be seen in acceleration. The change is provided by the different types of data we were able to collect when varying the slopes of the ramps, as well as the length of the track. Stability in this experiment came from us trying to get an average speed that the car went at. If it were to be released from the same exact place, with the exact same amount of force every time, it would produce a constant speed. This can be shown as a s sense of stability because having a constant speed gives a stable variable that can serve to be true in several situations.
