Prelecture Exploration: Cartesian and
Polar Coordinates
Dacia and Katarina are discussing the different coordinate systems used in their physics class, and they decide
to use a simulation to help their understanding.
They can click and drag the black point at the outer end of the brown line to various points in the xy plane and
see how its Cartesian and polar coordinates change in the readouts at the bottom. Note that 0 is defined as
the angle measured in a direction counterclockwise from the positive x-axis.

Part 1 of 10 - Importance of Different Coordinate Systems
Dacia asks Katarina why it is important to learn a new coordinate system, because they have been using the
Cartesian coordinate system and it seems to Dacia that it works fine. Which of Katarina's replies to Dacia are
correct? (Select all that apply.)
VP "Many objects move in arcs of circles or complete circles at times, and polar coordinates allow
the motion of such objects to be comprehended more easily. Some of Newton's laws in certain
cases, such as calculation of g from first principles, are much easier to calculate using polar
