Ch. 9 Rotational Kinematics
... Information is stored on a CD or DVD in a coded pattern of tiny pits. The pits are arranged in a track that spirals outward toward the rim of the disc. As the disc spins inside a player, the track is scanned at a constant linear speed. How must the rotation speed of the disc change as the player’s s ...

Chapter 7 Hooke`s Force law and Simple Harmonic Oscillations
... Problem: One atom of a diatomic molecule feels a force given by F = −C/r2 + D/r3 where C and D are positive constants. A) At what point does equilibrium occur? B) Will this atom exhibit simple harmonic motion for small oscillations? C) What is the force constant? D) What is the period of the motion ...

Classical mechanics
... Physicists tend to use the term "classical mechanics" rather loosely. Many use it for the mechanics of Newton, Lagrange, and Hamilton; for these people, "classical mechanics" excludes relativity and quantum mechanics. On the other hand, in some areas of physics, there is a tendency to include relati ...

Centripetal Force Video Script
... Did you say that velocity involves both speed and direction and that during circular motion, direction is always changing? That means velocity is changing. According to Newton’s 2nd Law, acceleration requires a net force. And that’s the centripetal force. Now there are four variables that could affe ...
