Before we can consider the rotation of anything other than a point mass like the one in Figure 2, we must extend the idea of rotational inertia to all types of objects. To expand our concept of rotational inertia, we define themoment of inertiaIof an object to be the sum ofmr2for a...
So here is a difference between linear and angular motion, with linear motion (provided there is no air resistance) it can move in all directions equally, regardless of the shape of the object. With rotation the direction of spin may be dependent on the orientation of the object (and visa ...
For purely rotational motion the kinetic energy, about its centre of mass, of a solid body is:T = 0.5 wt [I] wSo if we have combined linear and rotational motion can we just add the kinetic energy due to these parts separately? I think the answer is no because the energy of a ...

Astrophysicists at MIPT have developed a model for testing a hypothesis about supermassive black holes at the centers of galaxies. The new model enables scientists to predict how much rotational energy a black hole loses when it emits beams of ionized ma
The satellites in chaotic rotation can mimic ordinary regular synchronous behaviour: they preserve preferred orientation for long periods of time, the largest axis of satellite's figure being directed approximately towards Saturn. 展开 关键词: Resonances Chaotic motion Rotational dynamics Satellites of ...
