Σελίδα 71 - Newton's law of universal gravitation states that every particle in the Universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Σελίδα 177 - A seconds' pendulum is carried to the top of a mountain m miles high : assuming that the force of gravity varies inversely as the square of the distance from the centre of the earth, find the time of a small oscillation.
Σελίδα 176 - A body falls from rest from a height so great that the fact that the force of gravity varies inversely as the square of the distance from the center of the earth cannot be neglected.
Σελίδα 76 - The third, viz. that the squares of the periodic times are proportional to the cubes of the mean distances...
Σελίδα 141 - The Parallelogram of Forces. — If two forces acting at a point be represented in magnitude and direction by the adjacent sides of a parallelogram, the resultant...
Σελίδα 108 - ... the CGS unit of work, or what is, for purposes of measurement, equivalent to this, the CGS unit of energy, energy being measured by the amount of work which it represents. The CGS unit of power is the power of doing work at the rate of one erg per second, and the power of an engine (under given conditions of working) can be specified in ergs per second. For rough comparison with the vulgar (and variable...
Σελίδα 142 - If two velocities imparted simultaneously to a particle be represented in magnitude and direction by two adjacent sides of a parallelogram...
Σελίδα 47 - Laws ; it being remembered that, as the properties of matter might have been such as to render a totally different set of laws axiomatic, these laws must be considered as resting on convictions drawn from observation and experiment, not on intuitive perception.
Σελίδα 15 - The specific gravity of a substance is the ratio of the density of the substance to that of water. This quantity is thus a pure numeric, and tells how many times a substance is as "heavy
Σελίδα 34 - The equation W= mg is a numerical one, and means that the number of units of force in the weight of a body is equal to the product of the number of units of mass in the mass of the body, and the number of units of acceleration produced in the body by its weight.
