    I don't understand the context of the 5th question of the Dynamics- Friction worksheet

    Absolutely... want you to be 100% satisfied with your purchase. Refund complete.
  16. Jack Wang
    This PDF version can't highlight, can't add notes, I really regret bought it and would like to return it. I'd rather buy the Kindle version. Can I return it?
  17. Maker started following Physics of Kite Flying
  18. Maker
    Tails are not required for kites to fly. Tails are one method of stability. It is not necessary to run to launch a kite. There is a book on amazon.com that answers these questions clearly. It's called, "Kite Physics." It gives a visual explanation of the physics of kites in flight. With 125 pictures, illustrations, and 65 experiments. It answers the questions: Are tails required on a kite? How can I improve the flight of my kite? What are the forces that act on my kite? What changes can I try? Do kites glide? What are some applications of kites that I can explore? How do kites fly?

    Vertical jump training is essential for athletes as it helps them to perform better in the field. However, some people also try to follow these techniques to improve overall health and fitness.

    Correct. When you purchase the book it specifically says it cannot be printed (part of the licensing deal with publishers). However, all of the question sets are available to print individually at https://www.aplusphysics.com/courses/regents/worksheets/ws_index.html.

  51. FizziksGuy
    Connecting to ground provides an infinite supply of electrons (or can be an infinite sink of electrons). If you ground a metal rod, and hold a negative rod near an end, negative charges will be repelled from the rod into the ground. If you then disconnect the rod from the ground, no charges can enter or leave the rod, so you're left with a net positive charge on the rod.
