      do you never lay awake at night and think oh I still dropped ten percent .to be honest they should have told me,that we regret to inform you that you scored minus ten percent on your lifetime test exam!I might have to sweep floors and scrub toilets for fifty cents an hour! I jest good sir! What a performance,! Imagine if you scored ninety percent with the ladies!you'd be living in Caesar's palace before your nineteenth birthday!ninety percent,? This is a very difficult subject.you didn't, even have the answers in front of you!

    Good day! I'd like to ask, Kepler's 3rd Law in valid only in our Solar System or another (solar) systems, too, (most likely) pls ? And how about the g (constant 6,67 x 10^-11) ? Thx

    • @carultch
      @carultch 3 роки тому +1

      Planetary system is the general term for a group of planets orbiting a parent star. The solar system is the sun's planetary system specifically, since Sol means sun.
      Kepler's third law is valid in other planetary systems as well, but only among the planets that orbit in that particular planetary system. A hypothetical planet orbiting the sun at 8 AU would have an orbital period of 4 years, which fits Kepler's third law with the planets of the solar system. However, don't expect a planet orbiting a completely different star at the same 8 AU distance to also have an orbital period of 4 years.
      It is uppercase G that has a value of 6.67e-11 N-m^2/kg^2, and to the best of our knowledge, this is a universal constant. Lowercase g is gravitational field strength, and is specific to an individual world.

    • @sup2day
      @sup2day 3 роки тому

      Your question regarding the semi-major axis is astute but it turns out that the semi-major axis is the same for a circular or elliptical orbit having the same period. The key is that in an elliptical orbit, one can no longer state that the semi-major axis is equivalent to the radius. It must be defined as 1/2 the length of the entire major axis of the ellipse. Since the Sun does not occupy the center of an elliptical orbit you must shift your perspective away from the circular image provided by Professor Anderson, and envision an ellipse with the Sun at one of its foci. In this case, the Sun’s position has nothing to do with how we measure the semi-major axis.

    • @sup2day
      @sup2day 3 роки тому

      Professor Anderson has simplified the problem to that of the Earth in a circular orbit around the Sun. This allows for two simplifications. First, the radius r can be assumed to be equal to the semi-major axis. Second, the Sun’s mass far exceeds the Earth so that it can be assumed to be at the center of the circle. There are more general derivations based on the center of mass for both bodies but my attempts to link you to them have been blocked.

      Kepler's laws are derived from Tycho Brahe's observational data. Newton came up with his law of gravitation to prove Kepler's laws, from the fundamentals of how he believed the mathematics of gravity would work.
      The multiplication of masses in Newton's law of gravitation is a direct consequence from the empirical observation that force of gravity is proportional to mass, and Newton's third law that gravity like all forces is a two way street. The inverse square part of the law comes from the way a field with no divergence would spread out in space from a spherically symmetric source. Putting these together, we get the M*m/r^2 part of his law of gravity, and the big G is a constant of proportionality to make the units work out. Cavendish's experiment, over a century later, was the first to measure the big G.

    Sir...how can I practice mirror writing like you

    • @carultch
      @carultch 3 роки тому

      He's not actually writing backwards. He uses a mirror between the camera and the transparent board, to film this.
      Students who see him teach in the flesh, will see the backwards writing on the board. On a screen to the side, they see a live feed of the footage you are seeing, so that the writing is legible.

    How the sun"s mass was calculated.
    (I understand that mass of earth could be calculated by considering "average" specific mass on earth.)

    Im an Indian student, but the way our teachers teach us is like they want us to memorise the things and not understand them. Everyone is in a rat race to remember everything for their exams but nobody clearly understands things. But i have to say american teachers do explain well along with yt indian teachers unlike indian school teachers.

      centripital acceleration = v^2/r
      accordng to 2nd law of newton f=ma
      hence centripital force=mv^2/r

      G MAN,
      Can you explain a bit more what you mean by that? There are, of course, "flaws" in Kepler's Laws that are only fully explained by general relativity, but it sort of depends on what you call "major."

    Why derivation for circular orbits when we know that orbits motion is elliptical m???

    • @yoprofmatt
      @yoprofmatt  2 роки тому

      Indeed you are correct. We're trying to simplify the physics. Circular orbit is an ellipse of ellipticity = 1. We approximate this to make sense with Newton's laws for circular motion. Since Earth is in a near circular orbit, it works great.
