Question

How do body in circular motion have acceleration though It has constant velocity?

Answer 1

In a circular motion even if there is a constant velocity the velocity vector undergoes a change in direction. This change in direction implies that there is an acceleration in the radial direction and is equal to:

`a_c=(v^2)/(r)`

Where:

`\begin{gathered} a_c=\text{ centripetal acceleration} \\ v=\text{ velocity} \\ r=\text{ radius. } \end{gathered}`
