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 ...
This states that the angular momentum is the product of I (the moment of inertia tensor) and ω. The moment of inertia is indeed a tensor (don't worry about that right now). If you like, you can ...
She can’t can’t change the angular momentum, but she can change the moment of inertia. By pulling the legs and arms closer to the point of rotation, the moment of inertia decreases and the ...
Its moment of inertia increases, so for angular momentum to remain constant, the rotational speed has to decrease. More to explore Swiveling Science: Conserving Momentum in a Spinning Chair, ...
While weight and mass might affect how fast an objects falls, moment of inertia is the key to speed today! Much like a figure skater pulling their limbs in to speed up a spin, the more mass an ...
