If the body has only translational motion then the rotational kinetic energy will be zero and only translational kinetic energy will be there.
And if the rigid body is rotating about it's any axis passing through'O' then both translational and rotational kinetic energy will be there . And if the rigid body rotates about it's center of gravity then translational kinetic energy will become equal to rotational kinetic energy.
If a rigid body rotates about its center of gravity, its translational kinetic energy is at...
Opgave 4.2 (energie en arbeid) Given is a rigid body where the translational speed of the center of mass is zero at all times and the rotational velocity vector at initial time to is wo and at end time te is we. The body has a moment of inertia tensor I. What is the change in kinetic energy of the rigid body during this time?
4) A rigid body rotates with constant angular velocity about a fixed axis. Show that its kinetic energy K and angular momentum L are related according to K = 5, where I is the rotational inertia.
If a rigid body is rotating about its central axis with a rotational kinetic energy of 3.78 J and it has a moment of inertia equal to 5.08 kg*m^2, what is its angular momentum? Answer in kg*m^2/s.
