Vedclass · Answer

(C) In circular motion,the linear acceleration $\vec{a}$ has two components:$1$. The tangential acceleration $\vec{a}_t$,which is directed along the tangent to the circular path.$2$. The radial (or centripetal) acceleration $\vec{a}_r$,which is directed towards the center of the circle along the radius.Since the tangent to a circle at any point is always perpendicular to the radius at that point,the angle between the tangential component $\vec{a}_t$ and the radial component $\vec{a}_r$ is $90^{\circ}$.

What is the angle between the tangential component and the radial component of linear acceleration for circular motion (in $^{\circ}$)?
