Overview of the First Quarter!

We learned so much in physics in this short first quarter! The first thing we learned was observations. We learned that qualitative observations deal with the appearance and qualities of the objects. Quantitative observations deal with measurements. We also learned about Accuracy v. Precision. We learned that accuracy is something right on point, while precision is when you are consistent in your trials, but not necessarily accurate. Next, we learned about standards and why they are important. Standards are important so that everyone follows the same units and that everyone can communicate with each other.

We then learned about motion and the four words that are the most important when talking about motion:

"All motion is relative."

The next thing asked would be:

"Relative to WHAT?"

From the unit of motion, we explored more kinematics and how to solve problems using variables. We learned about speed, velocity, distance, time, acceleration, and displacement. The equations are listed in one of my earlier posts (dat, vat, vad)!

One of the most important things we needed to learn this quarter were the GRAPHING RULES.

1. The slope of a position v. time graph is velocity.

2. The slope of a velocity c. time graph is displacement.

3. The area under the curve of a velocity v. time graph is displacement.

We learned so much!!

These are examples of the graphs we needed to make and analyze in our labs this quarter.
