***AP Physics 1 Thread 2014-2015***

The last diagram on this page pretty much answers the last question: http://www.physicsclassroom.com/class/circles/Lesson-4/Circular-Motion-Principles-for-Satellites

I think it’s because there’s a negative in that equation.

@glasshours chem and physics done, cya in apush

anyone?

@Gatortristan Same!!!

hahahahhahahaahha that last free response question murdered me. multiple choice wasn’t too bad though

@asappebble The second harmonic one? Also it wasn’t linear right?

Anyone?

@mayman I don’t think it was linear.

im not asking for answers or anything like that, but just a poll

did a single person understand the last part of the last frq???

what even was the question

@Mathman97 yes. Look up a diagram of what the question is asking for, and observe its motion. There are points where the question is correct.

@Mathman97 no

For what form @mathman97?

and wasn’t the object coming toward the the earth, not away

@aoo1997 what was the question about? All i remember is something about the velocity of second harmonic or something

I thought the last FRQ was easy…? Kind of confused by what they meant as “mark”, but I think I figured it out…

@glasshours I marked the middle and the last points, I think the correct thing was 4th and 8th point

@mayman - I barely remember the question, but wouldn’t the points of maximum displacement occur at the two antinodes?

I’m pretty sure I only got the one about free fall totally correct. For all the other ones I was like nope…

I circled the curve because curve are where acceleration occurs? probably not right tlol
