Answer:
Q 1. Answer : the relation between angular momentum and torque is the same as between the linear momentum and force. ... This is due to the Angular Momentum. The more angular momentum the object has, the more it tends to keep rotating. Angular momentum can be defined as the moment of inertia time's angular velocity.
Q3: If the kinetic energy of an object launched from the Earth were equal in magnitude to the potential energy, then in the absence of friction resistance it could escape from the Earth. vescape = mi/hr. g = gEarth.
