Magnets and superconductors
... Even a small country like Italy is worthy of mention in the magnetic levitation high speed trains sector. This is the case of UAQ4, (Università dell’Aquila university model 4), a train on a guide way or magnetic levitation train, or system in which there is no physical contact between the fixed part ...

What is angular momentum?
... is no net torque (the forces are internal)so L is a constant but the moment of inertia changes and since L = Iω as I decreases ω increases. So if I decreases by a factor of 2 then ω increases by a factor of 2. The kinetic energy is = Iω2 so if I decreases the kinetic energy increases by the amount o ...

Momentum - Sackville School
... If two objects of the same mass are moving in opposite directions but at the same speed (i.e. their velocities are different), the momentum of each object will be of the same magnitude but a different direction. A ‘+’ and a ‘-’ are often used to indicate the direction of momentum of moving objects. ...

Chapter 6 The kinematics of NGC1333
... Currently, the most widespread way to classify young stellar objects is through the classification scheme laid out by Lada & Wilking (1984) with the addition of the Class 0 by André et al. (1993). These classes are based on the shape of the spectral energy distribution with the addition that Class 0 ...
