With the polar description, we write the velocity and acceleration vectors for a point in terms of the polar unit vectors e_r and e_theta. Recall that e_r points outward from the observer O and the ...

As expected, the acceleration of P has both non-zero tangential and normal components. From the equation provided for speed as a function of distance traveled, the speed of P is monotonically ...
