lol brother that is totally what I have been going through these past 6 weeks or so. I have never taken a physics class or calculus class in my life I think Algebra II is the highest math class I had taken prior to this class.

Physics without calculus is a nightmare of memorizing equations.
With calculus you can easily derive all the equations as needed. |

Galileo did it without calculus
or Algebra he did it with Geometry |

Quoted: My son is taking AP physics in high school. It is a challenge for him. He has not taken calculus or trig yet so that in itself makes it a challenge even though it is not calculus based physics. He was totally lost until I gave him a primer on trig. Tonight he wanted me to help him with his homework which was projectiles, travel times, distances, heights, etc. I have a math/physics minor and thought piece of cake. We got through it but damn it is crazy how something so basic and simple in the physics world racked my brain after being out of school twenty years and not using it regularly. I’m guessing those problems occur in a vacuum as well. It gets much harder, and more useful, once you add the atmospheric effects. |

I’m guessing those problems occur in a vacuum as well. It gets much harder, and more useful, once you add the atmospheric effects. The math blows up when you add in drag to projectile motion. Especially when the drag is a function of speed in the gas/fluid. As you approach the speed of sound in the fluid you are traveling in their is a singularity at Mach 1. The low velocity Bernoulli equations fail. The fluid is no longer 'incompressible.' Standing pressure waves (AKA 'Mach waves') can form. |

Quote HistoryQuoted: I’m guessing those problems occur in a vacuum as well. It gets much harder, and more useful, once you add the atmospheric effects. Yeah, AP Physics 1 and 2 all exist in a vacuum and usually neglect other factors like friction, aside for the unit on friction. Quoted: The math blows up when you add in drag to projectile motion.

I hope it'll go well (or at least not terrible). |

I’m fucked if my kid is smarter than me and takes AP physics

I know the days of physical textbooks are ending (if not already ended), but being able to flip back through a textbook to refresh your memory and quickly look through reference materials is invaluable. I still have textbooks from college at my desk. I find that when I see things in the same format I learned them it is faster to look through and it comes back faster.
Kids these days will have the world at their fingertips but I don't think they will be able to "relearn" forgotten materials quickly like older generations could. |
