Paul enlists Nellie Newton to illustrate Newton's three laws of motion. Paul clarifies the equivalence of m/s2 and N/kg, and leads to Earth's gravitational field g. Paul illustrates momentum conservation with a two-fish system.) Paul poses and solves a problem involving Suzie Skydiver, who dives and attains terminal velocity. The "thermal inertia" of substances is explained, particularly water. Transverse, longitudinal, bow, and shock waves are discussed.
