At the beginning of this unit on motion, I knew very little information and could not comprehend and clearly understand what motion really is. Then we did projects and analysis's along with reading text from the books which helped me clarify any queries I had about motion.
To me, motion can only be occurring if you have a reference point that is either stationary or moving. A reference point is an object or place that can be used to determine whether an object's distance from another is changing. You would be able to determine if an object is in motion by picking a reference point that is stationary or moving, like the sun. For example, compare a pen on your desk in motion to your bed. This means that the pen is not in motion as the pen itself, is stationary and so is the bed. However, if you would refer the pen to the sun, the pen would be in motion as the sun in rotating and the distance between the pen and sun varies.
While studying about motion, we also learned about speed, velocity, and acceleration. Speed calculates the distance traveled per unit of time while the speed given in direction is the velocity. Acceleration is related to velocity because it is the rate at which velocity changes. An object can accelerate in three different ways: changing direction, increasing speed and decreasing speed. To take in all of this information with not too many doubts and questions, we had created Mind Maps which were easy to study from as they were color codes which allowed me to group information that related to each other, so it would be easier when it came to the chapter test.
