Unit 3

These two photos show a glimpse of what we did in class today. The focus of our class was on acceleration and using acceleration in real life situations. One of the real life situations that we experimented with is the one shown in the pictures above which is dropping two different sized balls. The question that was asked when we dropped these two balls was would the large ball be faster, would the small ball be faster, or would they be the same. We soon found out that they were of the same speed, even though one ball was significantly larger. 

We also went over multiple kinematics questions and I were tested on challenging problems. By using DAT, VAT, & VAD we were able to complete these problems. I found out that drawing a diagram is very helpful. I learned that for most problems the key is acceleration, as for DAT, VAT, & VAD acceleration is something you always need to know to figure out another variable. I also learned that in most problems acceleration is 9.8 or 10 m/s2 down . This is the acceleration for anything while on earth. 

Graphing:  We graphed cars going down ramps, and graphed balls being thrown up in the air. 

From these graphing exercises I learned that going up a slope means the object is slowing down, going down a slope means the object is speeding up. When a ball is thrown up it's acceleration is fast, but then slows and stops at the top, then goes down faster until it stops in someones hands.
