Rotational Dynamics
... Equation: F·r = I·; the units for rotational inertia are kg·m2/rad2. Rotational inertia and legs: short legs have less rotational inertia than long legs. An animal with shorter legs has a quicker stride than one with long legs (same is true for pendulums). When running, we bend our legs to redu ...
