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 ...

We can't say because there is insufficient information. A direction is required before we can describe the force properly. Displacement is a distance and a direction, eg \(170m\) south. Velocity is a ...

Velocity is always TANGENT to the path. Acceleration, in general, has BOTH tangential and normal components. The normal component of acceleration always points INWARD to the path. The tangential ...
