Answer: because of the translational and rotational motion of the football
Step-by-step explanation:
A kick or a well thrown football follows a projectile path while spinning. In football, creedence is given to the translational motion which is independent of the spinning rotational motion. Radian is good in analysing the path because the angle representing one radian, is such that the length of the subtended circular arc is equal to the radius of the circle.
