Here we discuss escape velocity of a spacecraft leaving the gravitational field of another planet. Every planet has an orbital speed and and an escape speed. All orbits are actually elliptical in shape. If we continue to add energy to an orbiting object, the ellipse will get larger and larger and eventually the shape will change from an ellipse to a parabola. all orbital shapes are actually conic sections. We discuss what conic sections are and how orbits work.

    Best teacher, you take any subject puts heart and soul into teaching.

    This guy is the first person I have " met" who can explain physics. He doesn't have only the knowledge but also the didactic to pass the information on with great clarification. This is what means to be a professor/ teacher. Many can have the knowledge but if they don't know how to explain the subject; the title of being a teacher doesn't make them a teacher.

    Man you do NOT get enough praise. All of your videos are amazing brother thank you so much for everything you put into them. 🤘🏽
  • @jackdimarco1734
    The best math and science teacher in the United States hands down! Thank you!

    Great introduction to a subject that has always been of great interest to me: orbital mechanics. When rendezvous of spacecraft became a thing during the Gemini program, I was perplexed by the apparent enigma of accelerating a spacecraft into a higher orbit, only to then have a lower orbital speed. That provoked my interest at that point!

    I feel like you'll soon do a lesson about Einstein's theory of relativity if you continue doing these kind of vids. I couldn't be more excited 🤩🤩🤩
  • @wkennedypsyd1
    I received my BS in mathematics in the early 90s. I would have loved to have had you as a teacher or a professor. Very well done. Thank you.

    Excuse my sniping from a concealed position. I enjoy your videos.
    At about 2min33s " delay the impact" implies the travel time would be extended.
    A technical inexactitude.
    It would go further, but it wouldn't take more time.

    Great presentation.. your a great teacher.
  • @jjsmallpiece9234
    A circle is just a special case of an ellipse, where the max and minimum axis are the same dimension. So arguably there are only 3 conic sections/shapes

    Jayson it's just another superb topic thanks Master.
