There's more to the knowledge I've gained from the Kerbal Space Program. First of all I couldn't get the screen shot to work; I guess the F1 key doesn't like me. And yes, I did just use a semi-colon outside of English class. But another very important thing I've learned through the Kerbal Space Program is how to correctly get a lot of power to your rocket. While I previously thought that either putting one engine at the bottom of stack of fuel tanks (the engine doesn't have enough power to l
A dear friend of mine and I have recently started playing NCAA Football 12 on his 360 and most of the time I win, thanks to my knowledge of physics. Because I understand the concepts of conservation of momentum, work, and air drag, I very often run the ideal football play - the running back slip screen. For this play, the offensive linemen break their blocks on some of the defensive players who are rushing the quarterback. Lured into the illusion that they can have an easy sack, these linemen
So, we've lasted half the year in Physics, and what better time than now to discuss how I'm feeling about this class?
Ups:
1) Physics C and BC Calc go well together. As I learn more in one class, it helps me understand something better in the other class.
2) It's interesting to learn more real world physics, such as air drag and taking friction into account, instead of learning the mechanics of a perfect world that doesn't exist.
3) Doing the same topics as last year, like momentum and ener
1) Don't worry about the time, it will just make you work slower.
2) If Mr. Fullerton says it's going to be on the AP, it's probably going to be on the AP.
3) Since the AP changes every year, test taking strategies can often come in handy more than trying to hammer in every single thing we ever learned in the entire year.
So, we all know that everyone in our AP-C Physics class has to be a nerd to be crazy enough to take this class, and i think we could come up with a lot of great nerd costumes. For spring potential energy and conservation of energy, someone could attach a spring to the front of his or her clothing and then run into people and bounce off with equal kinetic energy. Or, for centripetal motion, someone could carry around a rope which he or she hands one end of to random a random person and then run
Reiterating Charlie's most recent blog post, this independent unit has certainly seemed more difficult conceptually than the previous independent unit. As soon as I thought I understood something in the unit, another curve ball was thrown at me. Luckily, I discovered that Ampere's law and the Bio-Savart law are extremely helpful and applicable in this unit, and the right hand rules and simple force equations (like F=q(v x and F = I(B x L)) are easier this year because of the practice we had w
In my computers class we looked up mind teasers on mindcipher.com in order to improve our problem solving abilities, but problem solving is certainly applicable to physics and this question was relatively easy but got your brain working a little bit:
You need to tell time for 30 seconds but all you have is a non homogenous rope (some parts burn faster than others) that you know burns for 60 seconds and a match. How do you tell time for 30 seconds?
And if that one is too easy:
It's said tha
Although I had to quit indoor track because of an ankle injury, I did learn a lot about the precision of triple jumping form from my coach. Previously, I had run my approach with my chest not perpendicular to the ground but slightly more forward and my knees did not move very high. With this form, my momentum (which points perpendicular from my chest) was pointed into the ground, preventing me from jumping as far as possible. My knees also needed tweaking, since a lot of the power from jumpin
If you have ever watched Hot Rod, one of my favorite movies, then you understand the joy/hilarity of poorly thought out stunts. My brother and I have always enjoyed puting ourselves in harms way of the purpose of an awesome video, but I've discovered that we are much more willing to do painful stunts if we are landing into water instead of on solid ground. Most recently, we went to some pier that was 10 or so feet off of the ground and attempted backflips on our bikes off of a ramp into the wa
Ping Pong has always been one of my favorite leisure time activities, and after embarrassing a good friend of mine yesterday with my ping pong skills, the physics of the sport came to mind, especially the physics of my favorite shot: the top spin shot. Arguably the most effective shot, the top spin increases your accuracy with more powerful shots, and is very difficult to return. But why?
The picture above shows how the spin of the ball forces the air below the ball to take a longer path,
No doubt, the weakest part of my tennis game is returning hard serves. I often try to hit powerful shots, so i take a large backswing. But, when returning a serve, the ball already has a high velocity, so a large backswing is not needed to hit the ball back with a high velocity. Actually, a small swing is much more effective and accurate. This is because of the principle of momentum. When hitting a serve, a large swing is necessary to give the ball a high speed because the ball, right befor
As we dive into impulse and momentum in this independent physics unit, I am reminded of my only car "crash" I've ever experienced, if you can even call it that. When I was backing up in a small parking lot several months ago, the back of my car bumped into a small pole that I didn't see, jerking my car to a stop. Due to the minimum speed my car was moving at (5 mph or 2.24 m/s), my car was not damaged at all. So I was interested in finding out what speed it would have been damaged. Given tha
I have always failed at writing down 50 equations in 4 minutes, both last year and this year, and I was never really sure why because I do know a good deal of equations. But as I think about it, I usually try to think of every little equation - getting me flustered and slowing me down - instead of focusing on the general equations that can help me figure out other equations. So, here's a simplified equation dump of equations that can lead you to most any equation we've learned in mechanics.

As my last blog post of the quarter, I think the only reasonable thing to do is get sentimental (at least as sentimental as you can in a physics blog post) and think of the ups and downs of this quarter. This quarter was mostly independent units, which was good in the fact that it helped prepare us for college but also made me realize that I need to change a lot of my study habits - or lack there of. I also have discovered that E&M comes a lot less naturally than mechanics did, so studying
Many people do not enjoy plane rides because of the uncomfortable feeling of their ears popping as the plane rises. This has to do with air pressure, a concept that is not really covered in AP-C Physics but we did deal with last year and is certainly important in understanding the general physics around us. As the airplane increases in altitude, the air becomes less dense (since less air is being pushed down by gravity), leading to a decrease in air pressure. Because of this, the air trapped
Depressingly, I followed the whizzing ball as it flew past the 50, the 60, the 70, and even the 80 yard mark. Our costly (both with time and money) trebuchet could not compare to the spring loaded demon of a catapult that bested our yardage by 44. But, this project certainly did improve my engineering knowledge. Comparing my trebuchet to another very similar one that flung the softball farther, I saw that with a stiffer structure, we could have had more success. If we had used screws instead
