willbe, ݐIf the particle describes one complete revolution then, The angular velocity is measured in radian second-1.Its dimensional formula is [T-1].
Uniform Angular Velocity
If the particle describes equal angles in equal intervals of time then the angular velocity is said to be uniform. Angular acceleration is the rate of change of angular velocity with time. Here, n2and n1 are the number of revolutions made by the particle in one second.Angular acceleration is measured in radian sec-2.
Its dimensional formula is [T-2].
Equations of Motion for Rotational Motion
For translatory motion, the equations of motion are as follows,For rotational motion, the equations of motion are analogous to that for translatory motion. These are,
Mathematical Derivation of the First Equation of Motion for Rotational Motion Let ɘbe the initial angular velocity and ɘbe the final angular velocity after time t. This equation is known as the first equation of motion for rotational motion.It describes therelation between initial angular velocity, final angular velocity and angular acceleration.
Mathematical Derivation of the Second Equation of Motion for Rotational Motion For translatorymotion, the displacement is given as, Similarly for rotational motion, the angular displacement is given as, From the first equation of motion for rotational motion we have,Thus on substituting we get,
This equation is known as the second equation of motion for rotational motion.It describes the relation between initial angular displacement, angular velocity, angular acceleration and time taken.
Mathematical Derivation of the Third Equation of Motion for Rotational Motion For rotational motion, the angular displacement is given as,We know that,
