In physics, you can apply Hookeâs law, along with the concept of simple harmonic motion, to find the angular frequency of a mass on a spring. And because you can relate angular frequency and the mass on the spring, you can find the displacement, velocity, and acceleration of the mass. Hookeâs law says that F [â¦]
Angular momentum [edit]. Angular momentum of an object revolving around an external axis O is equal to the cross-product of the position vector with respect to O and its linear momentum. Angular momentum of a rotating object is equal to the moment of inertia times angular velocity.Torque is equal to moment of inertia times angular acceleration, which is also equal to the change in angular momentum divided by time taken.Rotational Kinetic Energy is equal to one-half of the product of moment of inertia and the angular velocity squared.IT IS USEFUL TO NOTE THAT.ngular momentum [edit]. Angular momentum of an object revolving around an external axis O is equal to the cross-product of the position vector with respect to O and its linear momentum. Angular momentum of a rotating object is equal to the moment of inertia times angular velocity.
