Rotational motion pdf notes, important questions and synopsis synopsis a rigid body is a solid body of finite size in which deformation is negligible under the effect of deforming forces. Its motion down the plane is such that all the particles of the body are moving together, i. This physics video tutorial provides a basic introduction into rotational motion.

Systems of particles and rotational motion 143 axis, every particle of the body moves in a circle, which lies in a plane perpendicular to the axis and has its centre on the axis. Download rotational motion physics notes for iitjee main and advanced examination.
Torque equation 825 is the rotational equivalent of newtons 2nd law for linear motion. It tells us how difficult is to set an object in rotational motion. Aside from a possible constant velocity drift in the absence of. In the figure below, the two cylinders have the same masses. The equations for rotational motion with constant angular acceleration have the same form as those for linear motion with constant acceleration. This collection is very useful for jee candidates to crack their upcoming jee. Rotational motion physics, basic introduction, angular. It describes the difference between linear motion or translational motion and rotational motion. In physics, weve already shown how to account for the translational motion of the center of mass. Motion motion is defined as the change in position of an object with respect to time and its surrounding. The rotational inertia depends not only on the mass of an object but also on the way its mass is distributed around the axis of rotation.
