Paul clarifies the equivalence of m/s2 and N/kg, and leads to Earth's gravitational field g. Compared to the law of gravity, with examples. Dispersion and the roundness of rainbows is discussed. 18 -- Liquids I -- Sweet Conceptual Physics By Paul Hewitt Paul poses and solves a problem involving Suzie Skydiver, who dives and attains terminal velocity. Compared with electric potential energy, with novel situations.
Paul links central kinematic definitions and equations to Barry Biker. Liquid pressure depends on the density and the height, not the volume. A problem solution, nicely simplified, to acrobats Ari, Bari, and their dog Bo. Paul illustrates momentum conservation with a two-fish system.) Paul shows how a simple lever lifts a load, and how Nellie Newton lifts loads with a pulley systems.
