... moment of inertia I decreases. Hence the angular speed (which is the magnitude of the angular velocity vz) must increase in order for the magnitude of Lz = Ivz to remain constant. 8-13 (d) The angular momentum L of a system is conserved only if no net torque acts on the system. This isn’t the case ...

... previous problem about a vertical axis that passes through its center of mass. 19. A uniform cylindrical grinding wheel of mass 5.00 kg and radius 20.0 cm is turned by an electric motor. Once it is turned on it takes 10.0 seconds for the wheel to go from rest to 125 rpm. Ignore friction in the beari ...

... (no spin) P2 • Answer: The cue ball stops dead on impact and red ball moves forward with the same velocity (magnitude and direction) as that of the cue ball prior to impact! • Why?...Because both KE(= ½.m.v2) and momentum (m.v) are conserved on impact. • As the masses of both balls are the same the ...

Collisions and rotational kinematics
... In angular motion (and many other areas of physics) it is much more convenient to use radians (abbreviated rad) rather than degrees or revolutions to measure angles. To convert you just need to remember 1 revolution (1 rev) = 2π radians (2π rad) = 360 degrees (360°) ...
