Acceleration Part 2 (1/17 - 1/19)

Summary:

      Acceleration is the change in the velocity of an object over time. There are a few ways to make an object accelerate. You can roll off an object from an inclined surface and due to gravity, it will move down the inclined slope and accelerate. The other way is to input energy into it. An example of this the combustion of gas in order to power the pistons which increase the speed of a car. The formula of acceleration is: (V2 - V1) - (T2 - T1). The equation means to divide the change in velocity and divide it by the change in time. The quotient is measured in length/time^2. To write acceleration on a position/time graph, change the slope of the line over time and to write acceleration on a velocity/time graph, change the y-axis direction of the line.

SP4 - Analyzing and Interpreting Data:

     This week I completed the acceleration lab activity. The goal of this experiment was to learn how to measure acceleration and further understand how it works. I achieved that by analyzing and interpreting the data recorded. In the experiment, I worked with two other people in order to track the acceleration of a toy car. We put it on an inclined surface. When that happened, I called out the intervals of time and for each second, the two other people that I worked with pointed to where the car was for each second. We repeated the process two more times, inclined the inclined surface and repeated the process again. By the end of the experiment, there was a total of 3 trials. From those trials, we were asked questions to reflect upon acceleration such as how to calculate and measure acceleration and were asked to graph it on.
