- Translational Motion: The two forces are unequal and opposite, meaning they do not sum to zero. There is a net force acting on the body. According to Newton's second law (F=ma), a net force causes linear acceleration, resulting in translational motion. - Rotational Motion: The two forces are not acting along the same line. This creates a couple or a torque about any point (unless the forces are along parallel lines offset from each other, which also creates a torque). A net torque causes angular acceleration, resulting in rotational motion.
A body is acted upon by two unequal forces in opposite directions, but not in one line. The effect is that the body will have
