Chapter 8- Rotational Motion
... It is clear that to make an object start rotating, a force is needed; Unlike in linear motion, the position and direction of the applied force matter as well. In the figure, the applied force will be more effective in opening the door than force assuming they both have the same magnitude. The angula ...

Meanwhile, the radial acceleration at points in the upper part of the chimney would increase to the point that the chimney is under tension, not compression. In actual collapses, the chimney frequently breaks maybe 70% of the way up while falling, and the low ...

Chapter 9: Torque and Rotation
... Torque is usually represented by the lower case Greek letter “tau,” t. When calculating torque, if the line of action passes through the center of rotation, the lever arm is zero, and so is the torque, no matter how large a force is applied. ...

Rotation
... Translation: body’s movement described by x(t). Rotation: body’s movement given by θ(t) = angular position of the body’s reference line as function of time. Angular displacement: body’s rotation about its axis changing the angular position from θ1 to θ2. ...
