When the accelerating force is uniform the acceleration will be uniform. The velocity at the end of t seconds, if the body starts from rest, will be v = at; whence a = t'; , and l = --a (1) The space passed over at the end of/ seconds is equal to the product of the mean velocity and the time, or L = /, or L = Y2 aP. The force of 1 lb. when applied to a mass whose weight is 32.17 lb. will produce an acceleration of 1 ft. per second per second when the mass is moving against no resistance (frictionless motion). A force of / pounds acting on a mass of 1 lb. will produce an acceleration of'/ X 32.17 ft. per second per second. The relation between force, mass, and.acceleration is given by the equation / = Ma = -W---a- . Substituting the value of a in terms of v: ABSOLUTE TEMPERATURE Physicists employ what is known as the absolute scale of temperature, based on the so-called absolute zero of temperature, at which point no molecular vibration exists. This zero is conceived as 491.6 deg. fahr. below the melting point of ice, or 32 deg. fahr., it having been discovered that an ideal perfect gas would change in volume by of its volume at 32 deg. for each 1 deg. change in its temperature at constant pressure. Thus, if 514 Chapter 33__Physical Units, Weights, Measures and Tables Table Properties of Saturated Steam3 515
