~Happy 10th post for all you Perry followers out there. All seven of you are awesome.
What science ideas did you learn?
This week in science class we learned more about functions and how to create motion diagrams. Although, at this point I am not so sure I completely understand functions. So I will try my best to talk about them.
How did you learn these ideas?
We learned about functions by using motion diagrams to discover ratios.
Like: x(t) = 21 (M/s) * t. That ratio means the uncertanty multiplied by the time is equal to 21 meters per second multiplied by time. Ratio's can be easily changed by also changing the"(M/S)" if you changed it to "ft/s" it could be feet per seconds or you can change the denominator: "(M/min)" Now it is Meters per minutes. To understand Motion diagrams you must realize you cannot curve the lines. Motion diagrams MUST be straight if you go in the opposite direction the arrows change direction. Right = going in the positive direction and Left = going the opposite; negative direction. The larger the line is the faster it is going, the shorter it is the slower it is going. In motion diagrams you must label the positive and negative directions along with adding an origin. Remember to label the velocity with "V1, V2, etc...." in each line. And when ever there is change in the motion be sure to add a delta; which looks like a triangle!
Why is it important to know this idea (What real world application is there)?
Some real world applications are if I was a bungie jumper and I wanted to track the motion of my jump off the empire state building I could use a motion diagram to label my velocity, my deltas, and my speed.
