What stuck?

Throughout this quarter we have gone through many different sections and vocabulary. Sometimes not everything sticks, for some it goes in through one ear and out the other ear. As I try to review some of the terms learned this first quarter of Physics we can see what really sticked.

We started this semester learning about measurements. Hawaiians had not very precise ways of measurement. They would use body parts to measure items but I don't think they took into account that everyone size of body parts differ. No two people are alike as they would say. We even focused a little on pendulums. We would measure the period of one pendulum swing. To my surprise, there are many different common day pendulums we see around us, such as a grandfather clock.

Next thing I remember is motion. All motion is relative to something. Motion has to do with confuisng topics such as  displacement, acceleration, and velocity. While also touching on vector quantities and scalar quantities. Scalar is only the magnitude quantity or described with a numerical value along. Vector is dealing with the quantity of magnitude and a direction.

I guess I did remember something from school, who knew?
