As the motor disk starts to spin one way, the rest of the platform spins the other way such that the total angular momentum is constant (and zero in this case).

After the small disk starts spinning, the big platform must spin in the opposite direction such that the two angular momentum vectors add up to zero (vector). Image: Rhett Allain When I turn the ...

Angular momentum is crucial to cosmic rotation. ... He explains that angular momentum caused the gas and dust to flatten into a disc, which led to the formation of planets orbiting the sun.

Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular ...

Conservation of angular momentum explains why an ice skater spins more rapidly as she pulls her arms in. ... Planets form from material in this disk, through accretion of smaller particles.

The researchers found that over a range of high temperatures and high angular momentum, planet-sized bodies could form a new, much larger structure, an indented disk rather like a red blood cell or a ...

Jets remove angular momentum from those systems, ensuring sustained accretion onto the central object. This illiustration depicts how positioning the water masers permits reconstructing the gas flow ...
