Rotational motion equations formula list.

Cascarano Formula Sheet Physics 4A Simple Harmonic Motion Angular Frequency Displacement Mass on a spring Velocity Simple pendulum Period Frequency j Thin hoop rotating on axis through any diameter of the hoop. From Work and Kinetic Energy the instantaneous power or just power is defined as the rate of doing work 10915 P d W d t. It is also called angular motion or circular motion.

Rotational motion refers to anything spinning or moving in a circular path. θ a r c r a d i u s s r radian. Where T is the the period V is the tangential velocity and m is the mass of the object.

If the object has one complete revolution then distance traveled becomes. If we have a constant net torque Equation 1084 becomes W. 20072017 Rotational work done by a toque 𝜏 𝜃 𝜃𝑓 𝜃𝑖 𝜏𝜃 𝜏 constant 1053 1054 Power in rotational motion 𝜏𝜔 1055 Rotational Kinetic Energy 1 2 𝜔2 1034 Work-kinetic energy theorem 𝑖 1 2 𝜔.

τ r x F rF sinθ n. 05112020 We can apply the definition of power derived in Power to rotational motion. Linear speed and tangential speed gives the same meaning for circular motion.

Torque or moment of a force about the axis of rotation. It is a vector quantity. 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.

Download Motion Classes Physics Sheets. The quantity mr 2 is called the rotational inertia or moment of inertia of a point mass m a distance r from the center of. Rotational Motion Cheat Sheet Tangential Speed Linear Speed.

Ceiling fan rotation rotation of the minute hand and the hour hand in the clock and the opening and closing of the door are some of the examples of rotational motion about a fixed point. 28122020 What Is Rotational Motion. The motion may be uniform ie the velocity v doesnt change or non-uniform but it has to be circular.

It can be defined as distance taken in a given time. Is final velocity and a is acceleration. Key Formulas 2 Pythagorean Theorem.

Rotational Motion Formulae List. Angular displacement its unit is radian r a d i a n. θ 2 θ 1 t 2 t 1 Δ θ Δ t rads.

Linear speed and tangential speed gives the same meaning for circular motion. Rotational Motion is defined as the motion of an object around a circular path in a fixed orbit. This article contains the chapterwise pdf download links of JEE Physics Sheets of Motion classes for JEE Mains and Advanced.

V v 0 a t v v 0 a t. 2πr which is the circumference of the circle object. Another important rotational motion formula is the rotational kinetic energy of an object.

The kinematics of rotational motion describes the relationships between the angle of rotation angular velocity angular acceleration and time. 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 mr 2 is analogous to mass or inertia.
