  3. how do I find an article on this
  4. Badminton is a Sport where players score points by striking a shuttlecock with their racket so that it passes over the net and lands in their opponent's half of the court. It involves various aspects of physics, such as aerodynamics, projectile motion, kinetic/potential energy etc..
  5. Tetris Gems Super Combo 547,156 New World Record!!! https://www.youtube.com/watch?v=R01-9wYwht8
  6. The one about the ice skater? Can you be more specific?
  7. I don't understand the context of the 5th question of the Dynamics- Friction worksheet
  8. Absolutely... want you to be 100% satisfied with your purchase. Refund complete.
  9. 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?
  10. 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?
  11. 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.
  12. 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.
  13. I cannot print out papers from the pdf :( It said it needs password for the document
  14. Hi ertugrultiyek. Sounds like a solid question. What have you tried so far?
  15. The electric field just above the surface of the conductor charged plate in a machine has a magnitude of 3x10^5 N/C a) Derive an equation to find electric field on the surface of a big conductor plate. b) What is the surface charge density (in C/m^2) on the above mentioned plate, assuming that is a conductor?
  16. Hey, (SPOILER ALERT) what do you think of projectile motion last sunday episode when the big projectile hit Rhaegal?
  17. Hi Myua, It's in the download section -- the previous "buy" button turns to a "download" button after you complete the purchase. To save you the trouble, however, I also e-mailed you the file.
  18. Where can I find the book to download? I already purchased it.
  19. A hollow sphere, solid sphere, and thin hoop are simultaneously released from rest at the top of an #incline. Which will reach the bottom first? Assume all objects are of uniform density. #RollingWithoutSlipping Want Lecture Notes? This is an AP Physics 1 Topic.

  20. Example: Determine the #Acceleration of a uniform, solid cylinder #RollingWithoutSlipping down an #Incline with incline angle θ. The rotational inertia of a uniform, solid cylinder about its long cylindrical axis is ½MR^2. Assume the cylinder starts from rest. Want Lecture Notes? This is an AP Physics 1 Topic.

  21. Rolling without Slipping is demonstrated and the equation for velocity of the center of mass is derived. A cycloid is demonstrated. Kinetic energy, distance, and acceleration of rolling without slipping is discussed. Want Lecture Notes? This is an AP Physics 1 Topic.

  22. Example: A 0.300 kg mass rests on a 0.395 m long, 0.764 kg, uniform wooden plank supported by a string as shown in the figure. If the mass is 0.274 m from the wall and the angle between the string and the plank is 32.1°, (a) What is the force of tension in the string? and (b) What is the normal force from the wall?
