My Knowledge on Motion

At the beginning of the unit I had next to no prior knowledge on the motion unit overall. But as I began the unit the little knowledge I had about this subject began to come back to me, I began to remember how to find the average speed, what is speed.
But I also learned about topics like a reference point that you use to see if motion is happening or not. From the reference point came out the relative motion, which explains why somethings seem to be in motion but can also not be in motion, its all relative to what you use as a reference point. It also told me about the International system of Units that uses meters to measure distance so that all measurements stay equal when scientist trade notes and conclusions.From motion comes out acceleration, I learned how to figure out how fast the object accelerates, final speed minus the initial speed divided by the time, will get the acceleration. Acceleration is not only increasing speed but is also decreasing speed and changing direction. All three of these changes in speed are was of an object accelerating. Something moves because of acceleration and how it compares to the reference point, even the tiniest movement is motion. That is most of what I had learned in the Motion unit, it helped me get a grasped on what is to come in science.
