Repeated motion of a body around its own axis and every particle of the body pointed towards the axial line which joins center of mass of whole body particles known as Rotational motion.
Rotating body displaces angularly. Rotating body exhibits angular displacement and angular acceleration.
Centre of mass of rotating body is geometrical centre for regular bodies.
System of particles directed towards axial line during rotational motion.
Displacement of rigid body which is fixed by a line called axis of rotation.
Speed of rotating body reduced by its rotational inertia.
Angular momentum of rotating body depends upon its angular speed and rotational inertia.
Centre of mass remains at rest but system of particles accelerating perpendicular to plane of axis during rotational motion.
Torque forces responsible for angular motion of particles about an axis.
Movement of harvester Axis of rotation of harvester parallel to ground.Entire mass of particles of the harvester turns into rotation.
Examples of Rotatory Motion
Motion of Road roller Wheel of Road roller has more mass and inertia.Angular speed of Road roller reduce by its rotational inertia.
Motion of Spinner Wheel Point of contact of spinner wheel is fixed.Axis of rotation of spinner wheel at any instant passes through its point of contact.
