... In our previous discussion of planetary motion around the Sun, instead of saying that the centripetal force is the gravitational force, as we did when we derived eq. (4.4), we could have obtained the same result by using the following reasoning: When a planet revolves around the Sun, there are two f ...

... A feather and a coin do not fall at the same rate in air because of air resistance, (a.k.a. air drag). Let’s begin with a little demo: (i) Drop a piece of paper - as it falls, it flutters, moves sideways due to air resistance. (ii) Crumple paper into ball – it falls faster, less air resistance becau ...
