Newton`s Second Law of Motion (Chap. 4)
... Speed of falling objects increases until drag force balances weight. When forces balance, zero acceleration so constant velocity. Speed for which air resistance balances weight called terminal speed. High terminal speed (better open the chute!) ...

... a) Cells and batteries supply current that always passes in the same direction. This is called direct current (d.c.). b) An alternating current (a.c.) is one that is constantly changing direction. c) Mains electricity is an a.c. supply. In the UK it has a frequency of 50 cycles per second (50 hertz) ...
