To start off our first quarter in physics we learned about
qualitative observations, quantitative observations, accuracy, precision, and
standards of measurement. A qualitative observation deals with the qualities of
objects. A quantitative observation deals with the number of objects. Accuracy
is when something is free from error. Precision is when you get the same value
multiple times, or when your numbers are gathered closely. Standards of
measurement are when everybody is on the same page with things. We have
standards so that they will be followed, and everything is the same. Next we
talked about motion. “All motion is relative! Relative to what?” Motion deals
with acceleration, velocity, distance, time, and displacement. When graphing
things in motion there are three graphing rules. The first is, “The slope of a
position vs time graph is velocity. The second rule is, “The slope of a
velocity vs. time graph is acceleration. The last is, “The area under the curve
of a velocity vs time graph is displacement. These things are overall the big
concepts we have learned about during this first quarter.
