Yup, great catch! Updating...
2. ## Space Engine

Absolutely beautiful. And you put that first video together? Great dramatic musical selection to go with it!!!

That is a FANTASTIC question, and to answer it, we need to understand that by accelerating at the top position, we're no longer maintaining a circular orbit, but setting up an elliptical orbit. If we increase the speed of the satellite in that top position, we've increased the kinetic energy of the satellite at that position. But a more complete orbital analysis must take into account gravitational potential energy. By increasing the kinetic energy at the top position, we'll trade that speed off for gravitational potential energy at the bottom position. The following web page goes into more detail (https://www.physicsforums.com/threads/orbital-speed-faster-is-closer.733175/), but the best way I've found to get a good feel for orbital mechanics is to play games. As mentioned on the thread above, Orbiter is a free game that will give you a good feel for it, but Kerbal Space Program is a lot more fun in my opinion (though it's not free). :-)

Hi Scott, The PDF book itself isn't printable due to licensing restrictions, however, you can print out all the original worksheets here: http://www.aplusphysics.com/courses/regents/worksheets/ws_index.html. The answer key is only available in electronic form.

I'm assuming you're attempting to use v=d/t and coming up with L/t. Recall, though, that this formula gives you AVERAGE velocity. V_f is equal to 2*average velocity under constant acceleration, which you can provide by: v_0=0 v=? d=L a t=t Solve vf^2=v_0^2+2ad to get v_f=Sqrt(2aL) Solve d=v_o*t+.5*a*t^2 to get a=2L/t^2 Combine those two equations to eliminate a and solve for vf to show vf=Sqrt(4L^2/t^2)=2L/t

I'm not sure I completely understand the question, but if I attempt to read between the lines, you're wondering why this isn't the same as a block sliding down a ramp. Recall for the box sliding down a ramp scenario, we're setting the motion of the box along the x-axis and 'tipping' our axes to line up with that motion. In this case, although it looks like a box on the ramp, the car is actually moving into or out of the page, not sliding down the ramp. The direction of its motion is centripetal as it goes around the curve, or directly to the right (along the x-axis)... so we don't tilt our axis in this problem. As the car's motion is along the positive axis, directly horizontal, that remains our 'reference' axis.

I'm hoping you get some good news too...
8. ## The Physics of Cruise Ships

Fantastic application of physics in soooo many ways. I'm always floored by aircraft carriers and how they're able to maintain such stability. Big ships are totally cool!

I also have a "microelectronics in high school" mini-unit that covers the basics of not only transistor functionality, but device physics, chip design, and manufacturing: http://www.aplusphysics.com/educators/STEP.html
16. ## Video Discussion: Mechanical Universe: The Millikan Experiment (12)

Name: Mechanical Universe: The Millikan Experiment (12) Category: Electricity & Magnetism Date Added: 2017-02-07 Submitter: FizziksGuy Episode 12. The Millikan Experiment: A dramatic recreation of Millikan's classic oil-drop experiment to determine the charge of a single electron.“The Mechanical Universe,” is a critically-acclaimed series of 52 thirty-minute videos covering the basic topics of an introductory university physics course.Each program in the series opens and closes with Caltech Professor David Goodstein providing philosophical, historical and often humorous insight into the subject at hand while lecturing to his freshman physics class. The series contains hundreds of computer animation segments, created by Dr. James F. Blinn, as the primary tool of instruction. Dynamic location footage and historical re-creations are also used to stress the fact that science is a human endeavor. The series was originally produced as a broadcast telecourse in 1985 by Caltech and Intelecom, Inc. with program funding from the Annenberg/CPB Project.The online version of the series is sponsored by the Information Science and Technology initiative at Caltech. http://ist.caltech.edu©1985 California Institute of Technology, The Corporation for Community College Television, and The Annenberg/CPB Project Mechanical Universe: The Millikan Experiment (12)

Yikes. Hope you're doing OK.

21. ## NEW FILE: WS: Momentum and Motion

Good Afternoon, This is designed as a problem to compliment the Regents and Honors programs of study with this website (hence its location in the Regents and Honors folder), in which the coefficient of friction for wood on wood is a given and is designed to be looked up in a reference table (see link below). And yes, the first box would experience friction, however, based on the problem statement, you know the velocity of the first block as it contacts the second block, therefore there's no need to calculate a reduction in velocity prior to impact. Then, following the impact, and knowing the coefficient of kinetic friction of wood on wood, you can solve for the horizontal launch velocity using Newton's 2nd Law, at which point this becomes a projectile problem. Links to reference table with friction information: http://www.aplusphysics.com/courses/honors/dynamics/friction.html I would agree, however, that if you didn't know the coefficient of friction, you'd be stuck.
22. ## Waffles are the best

I think it's safe to say you've never made waffles and pancakes? One is definitely faster, but it's not the waffles...
23. ## AP Physics 2 Videos

Hi Gio. APlusPhysics is just a single person, me, so that's pretty easy to answer. They are on my to-do list, but are at best a month or two away. Note that most of this material is covered to at least some depth in the "Honors" physics video series. Hope that helps! -Dan
24. ## Clean Rooms

Spent TONS of times in clean rooms, most of which at a cleanliness level thousands of times cleaner than surgical suites. There is a TON of money and engineering spent on creating cleanrooms -- fantastic career opportunities!
25. ## Squats Baby!!!!

And since it's about baby squats... gotta start 'em young!
