Rotational Kinetic Energy Calculator:

Enter the values of Mass of Moment of Inertia I_(kg) & Angular Velocity w_{(radians/sec)}  to determine the value of Rotational Kinetic Energy E_(J).

Rotational Kinetic Energy Formula:

The Rotational Kinetic Energy E_(J) in Joules is Equal to the 0.5 into Multiply the Mass of Moment of Inertia I_(kg) in kilogram and is Multiply the Angular Velocity w_{(radians/sec)} in radians per second is squared.

The Equation of Rotational Kinetic Energy can be written as,

E_(J) = 0.5 * I_(kg) * w²_{(radians/sec)}

Here,

E_(J) = Rotational Kinetic Energy in Joules

I_(kg) = Mass of Moment of Inertia in kilogram

w_{(radians/sec)} = Angular Velocity in radians per second

Rotational Kinetic Energy Calculation:

1) Calculate the Rotational Kinetic Energy and given for the Mass of Moment of Inertia = 15kg , Angular Velocity = 10rad/sec.

Answer

E = 0.5 * I * w²

E = 0.5 * 15 * 10²

E = 750J.

2) Calculate the Angular Velocity and given for the Mass of Moment of Inertia = 15kg , Rotational Kinetic Energy = 750J.

Answer

E = 0.5 * I * w²

750 = 0.5 * 15 * w²

w = 10rad/sec.
