The angular momentum is a quantity that we can calculate for rotating object. It's the product of the angular velocity (how fast it spins—represented with the symbol ω) and the moment of ...

When you look out of the window of a plane, everything looks so small. But they're all big enough to do some awesome physics.

Key concepts Physics Angular momentum Tension Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more ...

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...
