It is demonstrated in treatises on Rational Mechanics, that the
centrifugal force is proportional to the square of the velocity of Formulæ relating to Falling Bodies. The second and third laws rotation ; whence it follows that, under the same meridian, it of falling bodies may be respectively represented by the formulæ increases as we approach the equator, where it reaches its maxivagt, and sgt2.

Again, a body intensity. Now 289 being the square of 17, it follows that, if the which falls during t seconds by a motion uniformly accelerated, motion of rotation in the earth were 17 times slower than it is, the with an initial velocity equal to zero or 0, and a final velocity centrifugal force at the equator would be equal to that of gravity, equal to gt, will describe the same space as if it fell during the and all bodies on its surface in this latitude would be on the whole time t by a uniform motion, with a mean velocity between point of being projected into space. O and gt, that is, with the velocity ? gt. Now, in the latter As we proceed from the equator towards the poles, gravity is the motion being uniform, the space desoribed is equal to the less and less affected by the centrifugal force. This happens chiefly product of the velocity and the time; whence, denoting this space because the centrifugal force decreases in proportion as we recede by s, we have s=igt xt=19€ (2). The demonstration of from the equator, and also because that, at the equator, the conthese theorems is given mathematically in treatises on Dynamics; trifugal force is directly opposite to that of gravity, whereas, in sve Whewell's Mechanical Euclid, and other elementary works proceeding towards the poles, its direction becomes more and of the same description.

Thus, If in the formula (2) we make t=1, we have s=19, whence in fig. 15, in which pa represents the axis of the earth, and Er the 9=28; that is, the velocity acquired at the end of a unit of time is double the space described in that unit of time. This value of
is called the measure of gravity. Thus, in the latitude of Lon. don, it has been found that a body falling near the surface of the earth, in a vacuum, describes about 16 it feet in the first second of its fall; hence, the measure of gravity of London is about 32% feet; in other words, after a body has fallen 161, feet in 1 second, by the force of gravity, it would, if the attraction of the earth were removed or counteracted, continue to fall ever after with a uniform velocity of 327 feet per second.
In formula (1) the velocity v is expressed in a function of the time; that is, an expression involving the number denoting the time; but we can likewise express it in a function of the space described, by eliminating t from the two formulæ (1) and (2). For, from the first, we have t=%, whence t2

Length of the Compound Pendulum.-The preceding laws and formulæ are applicable also to the compound pendulum; but in this case it is necessary to define what is meant by the length of the pendulum. Every compound pendulum is formed of a heavy rod terminating in a larger or smaller mass, according to its form and purpose; now, all the different points of such a pendulum tend, according to the third law of pendulum motion, to describe their oscillations in times differing from each other, and increasing in duration in proportion to the square roots of their distances from the point of suspension. But all these points being invariably, connected together, their oscillations are necessarily performed in the same time. Hence, it is evident that the motion of the points nearer to the axis of suspension is retarded, and that of the
points more remote from that axis is accelerated, Between direction » Now, if the same construction be made at any these two extremes there are some points which are neither point of the arc un, it will be found that the grayity which accelerated nor retarded, and which oscillate as if they were not acted from m to M with an accelerating force will now act connected with the rest of the mass. These points being all at from u to n with a retarding force. It will take away, there the same distance from the axis of suspension, form together an fore, successively from the moveable the velocity acquired in axis of oscillation parallel to the former; now the distance of the its descent, so that, when it reaches the point n at a height axis of oscillation is called the length of the compound pendu fum. equal to that of the point m, the velocity will become zero, as Hence, the length of a compound pendulum is the same as the it was at the latter point. Whence it follows, that the length of a simple pendulum which performs its oscillations in same series of phenomena will be repeated, and the pendulum the same time. Thus in the preceding figure of the compound will continually oscillate.
