Smart Rotational Motion Formulae

You can quickly revise entire chapter here in a quick overview.

Rotational motion formulae. Experience some degree of spin or rotation. Many of the equations for mechanics of rotating objects are similar to the motion equations for linear motion. Make a plan to prepare for the chapter and Stick to a Timetable.

Where ω is the angular velovity r is the radius and v is the tangential velocity. Angular displacementθ average angular velocityx time t. To state this formally in general an equation of motion M is a function of the position r of the object its velocity the first time derivative of r v dr dt and its acceleration the second derivative of r a d2r dt2 and time t.

To determine this equation we recall a familiar kinematic equation for translational or straight-line motion. These list of physic formula of class 11 chapter Rotatory Motion is useful and highly. The moment of inertia of a body about a given axis is equal to the sum of the products of the masses of its constituent particles and the square of their respective distances from the axis of rotation.

You can make timetable according to available time left for preparation and try to prepare according to it. The rotational motion may be present along with translational motion. Rotation Equations These rotation equationsapply only in the case of constant angular acceleration.

V2πrtime where r is the radius of the motion path and T is the period of the motion. The rotational kinetic energy is dependent on the objects angular velocity moment of inertia and. ω 2πT2πf where T is the period of the motion and f is the frequency.

This last equation is the rotational analog of Newtons second law F ma where torque is analogous to force angular acceleration is analogous to translational acceleration and mr2 is analogous to mass or inertia. Its unit is kgm 2 and its dimensional formula is ML 2. Here you will get all the Rotational Motion formulas for class 11 JEE and NEET examination.
