Science 🔬 on Instagram: "Angular momentum is the measure of how much rotation an object has, taking into account both its speed of rotation and how its mass is distributed relative to the axis of rotation. It’s essentially the “spinning equivalent” of linear momentum. A key property is that angular momentum is conserved — meaning unless an outside force or torque acts, a rotating object will keep spinning at the same rate. This is why figure skaters spin faster when they pull their arms in, and
