Rotation and TorqueRotational motion, or spin, is visible everywhere; it is involved whenever an object changes its orientation. Our technical civilization relies on wheels and levers, and will continue to do so despite the modern engineer's justified abhorrence of "moving parts." In the natural...

Physics Lab#3 : Torque & Rotational Equilibrium Intro: Similar to the fact that a force is anything that can cause a linear acceleration, a torque occurs by any force that is able to cause an angular acceleration. Static torque exists when the syst...
rotational motion. The torqueLof a system of particles is defined asL= Σri×fi, whereriis the position vector of theith mass point with respect to some origin of a reference frame (often chosen to be the center of mass),fiis the external force acting on the same mass point, and the ...
To obtain a quantitative understanding of motor behaviour, we sim- ulated the rotational motion of a magnetic bead in an external field under the influence of thermal fluctuations, viscous drag, and a constant motor torque (Supplement S5). In addition, we fit the data to a simple model that...
