Physics

The judicious teacher will, of course, vary the questions according to
circumstances; and those who may not employ them at all, as questions,
will still find them useful, in directing the pupil to the most
important points, in every page.

The Glossary has been confined to such terms of science as occur in the
work; and is believed to include all those, of which a clear definition
cannot be found in our common dictionaries.




CONTENTS.


CONVERSATION I.

     ON GENERAL PROPERTIES OF BODIES.                               9

     Compound Motion, the result of two opposite forces. Of
     Curvilinear Motion, the result of two forces. Centre of Motion,
     the point at rest, while the other parts of the body move round
     it. Centre of Magnitude, the middle of a body. Centripetal
     Force, that which impels a body towards a fixed central point.
     Centrifugal Force, that which impels a body to fly from the
     centre. Fall of Bodies in a Parabola. Centre of Gravity, the
     point about which the parts balance each other.


CONVERSATION V.

     ON THE MECHANICAL POWERS.                                     54

     of the first kind, having the Fulcrum between the power and the
     weight. Of the Lever of the second kind, having the Weight
     between the power and the fulcrum. Of the Lever of the third
     kind, having the Power between the fulcrum and the weight. Of
     the Pulley. Of the Wheel and Axle. Of the Inclined Plane. Of
     the Wedge. Of the Screw.
