What is the primary difference between linear kinetic energy and rotational kinetic energy?

Linear kinetic energy involves forces, whereas rotational kinetic energy involves acceleration.

Linear kinetic energy is only found in non-rotating objects, while rotational kinetic energy is only found in rotating objects.

Linear kinetic energy depends on velocity squared, while rotational kinetic energy depends on mass squared.

Linear kinetic energy is related to motion along a path, while rotational kinetic energy is related to spinning motion around an axis.
