    so cool!

    I might start with a resource like this: https://opentextbc.ca/physicstestbook2/chapter/damped-harmonic-motion/ or this: https://www.toppr.com/guides/physics/oscillations/damped-simple-harmonic-motion/
  16. Muskkan started following Simple Harmonic Oscillator - Critically Damped
  17. Muskkan
    Well, in AP Physics class we are using Giancoli 6th edition book. It doesn't have equations for Damped simple harmonic oscillator. I looked at the following link: http://farside.ph.utexas.edu/teaching/336k/lectures/node19.html but I do not know how to get started. The given are Amplitude = .05 m, Time = 3.5 sec, Mass = .58kgs, k = 150 N/m and we nee to find Friction force.

    Hi Muskkan. Damped oscillators are outside the scope of AP Physics 1/2, but happy to help if I can. How far have you gotten so far / where are you getting stuck?
  19. Muskkan
    Can someone answer this: A critically damped simple harmonic oscillator starts from an amplitude of 5.0 cm and comes to rest at equilibrium 3.5 sec later. The simple harmonic oscillator is made of a .58 kg mass hanging from a spring with spring constant 150 N/m. Assuming the friction force is in the vertical direction, how big is the friction force?

    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..

    The one about the ice skater? Can you be more specific?
  26. HappyFunTimes
    I don't understand the context of the 5th question of the Dynamics- Friction worksheet
  27. FizziksGuy
    Absolutely... want you to be 100% satisfied with your purchase. Refund complete.

    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?
  29. Maker started following Physics of Kite Flying
  30. 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.

    I cannot print out papers from the pdf :( It said it needs password for the document

    Hi ertugrultiyek. Sounds like a solid question. What have you tried so far?
  42. ertugrultiyek started following !!Final exam!! Electric field Gauss'
  43. ertugrultiyek
    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?
