(c) Strike it opposite the hole you have made. Observe as above. ENERGY. Define;--Work, Energy; The units used in the measurement of forces, as: Gravity Unit, Absolute Unit, Dyne; Elements of Work-measure; Units of work; Foot-pound, Kilogrammetre; The Erg, The C. G. S. unit, as: The Gravity unit in Ergs =? A Foot-pound in Ergs =? Horse-power =? Determine the relation of Velocity to Energy, i. e. given V to find S. See Avery, Arts. 156 and 157. Define Physics. See Avery, Art. 12. 6. QUESTIONS. 1. How many horse-power in an engine that will raise ) lbs. 176 ft. in 4 seconds? 2. A ball weighing 85.22 kg is rolled with a velocity of 30 meters per second. How much energy has it? 3. A mass of 250 grams is moving with a velocity of 20 cm. a second; through what distance must a force of 60 dynes work in order to stop the motion? 4. A force of 72 dynes acts on a mass of 900 grams through 2 meters; what velocity has been produced? 5. A certain force pushes a mass of 200 kilograms up a smooth inclined plane rising one inch through 3 meters, the mass then goes on for half a meter more before it begins to return; find the force employed, supposing g = 9 80. MACHINES. See Avery, pages 87-113; Gage, Arts. 100 and 101. Exerc1se 158. In the laboratory will be furnished you a frame-work on which is mounted a standard. On this standard is mounted, by means of a movable rod, a wooden bar in which is a double row of holes. (a) Support the bar at its center and attach equal weights at the extremities. Does the bar remain in a horizontal position? Designating one weight by W, the other by P, the support by F, the distance from W to F by W F, and the distance from P to F by P F, find the product of P X P F and W X W F. Repeat several times, increasing P and W, ..
