Force, mass, and momentum are terms that you have probably encountered in everyday life, but you may have rarely seen torque, moment of inertia, and angular momentum used to describe the rotational motion of an object. Yet, we encounter a lot of rotational motion in our everyday lives. Why do you think we do not use torque, moment of inertia, and angular momentum as much as force, mass and momentum when describing everyday motion? Or do you disagree with the statement that the rotational terms are used less than the linear terms in everyday language? Explain your reasoning.
