Question

relation between kinetic energy and moment of inertia​

Answer 1

Answer:

A rotating object also has kinetic energy. When an object is rotating about its center of mass, its rotational kinetic energy is K = ½Iω2. Rotational kinetic energy = ½ moment of inertia * (angular speed)2. When the angular velocity of a spinning wheel doubles, its kinetic energy increases by a factor of four.

Answer 2

K=(1/2) * Iω².

• This equation shows that the kinetic energy of a rotating rigid body is inversely related to the square of the angular velocity and the moment of inertia.
• Flywheel energy-storage systems, which are intended to store enormous amounts of rotational kinetic energy, take use of this. Currently, many automakers are testing kinetic energy recovery systems, flywheels, and other forms of flywheel energy storage in their vehicles.
• Similar to translational motion, the moment of inertia is a quantitative way to measure rotational inertia, and mass is a quantitative way to measure linear inertia.
• In other words, the more massive an object is, the more inertia it has, and the more resistant it is to changes in linear velocity.

K=(1/2) * Iω².
