👉 Secundoprimary is a term used in physics and mathematics to denote an object that has both rotational and translational motion. It's often applied to objects that have two or more axes of rotation, such as a gyroscope, a wheel, or a pendulum. In the context of rotational motion, secundoprimes can be described as objects that rotate about a fixed point (the "pivot") in an object's plane of rotation without any external torque. This means that each axis of
