Description: A simple take-home lab in which students melt marshmallows in a microwave to experimentally determine the speed of electromagnetic waves in air using the wave equation and the given frequency of the microwave. Objective: Determine the speed of light experimentally Materials: Microwave Bag of marshmallows (preferably mini's) Casserole dish Butter Metric ruler Rice Krispies or graham crackers and chocolateFree -
Wow, nice job. Don't forget the negative sign for gravitational PE, Ug= -GMm/r

Some thermodynamics, some kinematics, some dynamics... lots of tricky stuff involved in spring weather!

Hi folks, As you may have noticed, the last 9 months or so of posts have disappeared… this occurred due to a combination of web hosting problems as well as operator (my) error in restoring backups. Thankfully, only those 9 months worth of posts have been lost, and I’m actively beginning efforts to migrate the entire site to a new host that should not only minimize the possibility of something like this recurring, but should also dramatically speed up the entire site while allowing much more room for future growth. My apologies for the inconvenience, and my thanks for your understanding. Source

Glad to see you reading Rhett Allain's blog as well. He does some pretty cool stuff! -
I'm never telling!

I'm a little scared after watching this clip... on oh so many levels!

Quickie off topic post

Very cool -- I had no idea! -
I'm with you... without a doubt, the course takes a step up in complexity when we get to E&M. The mechanics portion of the course is really about learning the new notation, learning a new way to attack what you don't understand, etc. Then you get to apply it when we hit electrostatics! Hang in there, though... it's amazing how things start to come together about a week after we finish induction as we prep for the AP exam!

Another item that might be of interest... one of our bloggers checked it out already and gave it her seal of approval! Barron's AP Physics C Review Book Let's make it happen! And a review of Barron's AP Physics C Review Book

They found it in the drawer a month or so ago!

Einstein's "spooky action at a distance"

Very cool, and great to hear from you! -
I reckon that's a nice summation of a truckload of material from the unit. Good job pardner.

Thanks for helping out our forum members!

I would start with the dimensions... if the rocket must cross the airplane's path 1km in front of airplane, and you also know the angle, you can use trig to determine how far the rocket should fall. Once you have this distance, it's just a free-fall problem! (I'm betting the diagram where you show the "must be at least 1 km away from airplane" is probably off. The line from the front of the airplane to the intersection of the plane's path and the rocket's path should be 1 km if I understand correctly.) Maybe try re-drawing the diagram, then seeing what you know from the triangle made up of the plane's path (horizontal line), the rocket's fall (vertical line), and the hypotenuse (the rocket's path). Slick problem, I like it!

The negative sign on the height just indicates that the ball is lower than when it started. Your teacher is calling the launch height 0, and determining when the ball crosses the net it has fallen that amount vertically. Check out our projectile motion tutorials/videos as a starting point and see if that helps. If not, if you can give us an idea of what you're thinking, what you've figured out so far, and where you're stuck, it will make providing assistance much more straightforward. Good luck!
