86. lappuse - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
42. lappuse - Every particle of matter, in the universe, attracts every other particle with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
92. lappuse - Parallelogram of Forces. If two forces, acting at a point, be represented in magnitude and direction by the...
43. lappuse - It is well known that the earth is not a perfect sphere, but is flattened at the poles, being what astronomers call an oblate spheroid.
180. lappuse - The calorie is the amount of heat necessary to raise the temperature of one gram of water one degree centigrade.
68. lappuse - ... the ratio of the ovendry weight of a sample to the weight of a volume of water equal to the volume of the sample at some specific moisture content, as green, air-dry, or ovendry.
97. lappuse - If two forces acting at a point be represented in magnitude and direction by the adjacent sides of a parallelogram, the resultant of these two forces will be represented in magnitude and direction by that diagonal of the parallelogram which passes through the point.
196. lappuse - TJiefucl value of food. — Heat and muscular power are forms of force or energy. The energy is developed as the food is consumed in the body. The unit commonly used in this measurement is the calorie, the amount of heat which would raise the temperature- of a pound of water 4° F.
178. lappuse - ... together a pound of mercury, heated at 50 degrees, and a pound of water heated at 100 degrees, the temperature of the mixture, instead of being 75 degrees, will be 80 degrees ; so that the water will have lost only 12 degrees; whilst the mercury will have gained 38 degrees; from which you will conclude that the capacity of mercury for heat is less than that of water. Caroline. I wonder that mercury should have so little specific heat. Did we not see it was a much better conductor of heat than...
143. lappuse - ... not the hour as usually understood and practically used ; yet there is nothing in the context to indicate the distinction between the sidereal and mean solar hour. The other doubtful statement is on p. 290, where we read : " Any change in the direction or speed of a moving body is produced by force. When a force acts in either of these ways it is said to do work.
