Academic team of Entrancei prepared short notes and all important physics formula and bullet points of chapter Rotatory Motion class-11 Physics. In uniform circular motion speed of the object is always constant and direct rotational motion imagination is changing and as a result object has acceleration. Here I is analogous to m in translational motion.
Moments of inertia are represented with the letter I and are expressed in units of kgm2. Is final velocity and a is acceleration. Torque or moment of a force about the axis of rotation.
Thus velocity of the object is changing and as a result object has acceleration. To determine this equation we recall a familiar kinematic equation for translational or straight-line motion. System of Particles.

Rotational motion equations formula list. Let us start by finding an equation relating ω α and t. ω i n s lim Δ t 0 Δ θ Δ t d θ d t.
The kinematics of rotational motion describes the relationships among rotation angle angular velocity angular acceleration and time. ω2πT2πf where T is the period of the motion and f is the frequency Angular Acceleration Centripetal Acceleration. Some concepts will be covered in this units.
Mechanical Properties of Fluids. Or where ω is the angular velovity r is the radius and v is the tangential velocity Centripetal Force. F mv2 r mrω2.
Centrifugal force- Centrifugal force is the fictitious force which acts on a body rotating with uniform velocity in a circle along the radius away from the center. It is a vector quantity. Centripetal and centrifugal forces are equal in magnitude and opposite in direction.
θ a r c r a d i u s s r radian. Kinetic Theory of Gases and Thermodynamics. Another important rotational motion formula is the rotational kinetic energy of an object.
The rotational kinetic energy is dependent on the objects angular velocity moment of. V2Ï€rtime where r is the radius of the motion path and T is the period of the motion. Rotational speed angular speed tangential speed linear speed frequency period rotational inertia of the objects torque.
That is I m r 2. 06Work Energy and Power. These list of physic formula of class 11 chapter Rotatory Motion is useful and highly recommended for quick revision and final recap of chapter Rotatory Motion.
