Σελίδα 87 - 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.
Σελίδα 248 - 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.
Σελίδα 140 - The total energy of any material system is a quantity which can neither be increased nor diminished by any action between the parts of the system, though it may be transformed into any of the forms of which energy is susceptible.
Σελίδα 197 - IV. // any number of forces acting at a point can be represented in magnitude and direction by the sides of a polygon taken in order, they will be in equilibrium.
Σελίδα 247 - Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
Σελίδα 197 - If three forces acting at a point be in equilibrium they can be represented in magnitude and direction by the sides of a triangle taken in order.
Σελίδα 89 - Change of motion is proportional to the impressed force, and takes place in the direction of the straight line in which the force acts.
Σελίδα 236 - Kelvin has shown that if a drop of water were magnified to the size of the earth the molecules of water would be of a size intermediate between that of a cricket ball and of a marble.
