In science class, we worked on motion graphs and how to create different patterns. Here are some of the lines we attempted to recreate by using a motion sensor.
Our first goal was to create a straight line, and we did this by keeping the motion sensor still.
Our second goal was to create a line that increased and decreased slowly. To do this, I walked towards the motion sensor at a constant speed, and walked away from the sensor at the same speed.
Our third goal was to create a zig zag, and we created this by moving back and forth in a fast speed.
After completing Part A of graphing, we moved onto the next challenge, to try to recreate a line. To complete the first challenge, we used the ceiling and moved the sensor up and down. We first started a meter from the ceiling, holding the sensor above our head. Next we tried to lower the sensor in order to follow the increase in slope. We tried to keep the sensor still to create the straight line, and then we slowly stood up again, ending with a straight line, as shown on the graph.
After multiple challenges, we moved onto the next challenge, Part D. (We were told to skip C as we were running short on time and we should try a graph with velocity as the y axis). Although we were not very successful, to recreate the graph here, we used a white board, and one of us walked back and forth. Zen first stayed still, and then moved back quickly in order to create the vertical line. Next, Zen walked back maintaining the same speed (0.5 meters per second). I took a giant leap forward, stayed still, and took another leap forward, and ended by walking at the same speed as before, however in a different direction (0.5/s). As you can see, it wasn’t successful.
Lastly, we tried to complete task E. Here, we had to start by walking backwards in a slowly increasing speed. Next, we tried to keep that speed, followed by a giant leap towards the sensor. Then we walked in a fast speed in a forward direction, ending it with sudden stop. As you can see, we couldn’t do it successfully at all.
