Stran 18 - Newton's law of gravitation states that every particle in the universe attracts every other particle with a force which is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them, the direction of the force being in the line joining the two points (ref.
Stran 7 - From this illustration we see that the moment of a force is numerically equal to the product of the magnitude of the force and the perpendicular distance from the axis, or pivot, to the line of action of the force.
Stran 61 - Any two particles of matter attract each other with a force which is directly proportional to the product of the masses and inversely proportional to the square of the distance between the two particles.
Stran 85 - ... in which W is in limiting equilibrium is 2 tan"1 \i. 38. A rod of length 2/ rests with one end in contact with the inner surface of a rough hemispherical bowl whose rim is horizontal ; the upper end of the rod projects over the edge of the bowl and the vertical plane through the rod passes through the centre of the sphere. If a is the radius of the sphere and X the angle of friction at both points of contact, show that in the limiting position of equilibrium when the portion of the rod inside...
Stran 201 - In general the largest current from a given number of cells will be obtained when they are so grouped that the internal resistance of the battery is equal to the external resistance of the circuit.
Stran 210 - ... intensity of the magnetic field, and the sine of the angle between the lines of force and the direction of the current. This may be more concisely expressed by saying, that if a conductor carrying a current is moved in a magnetic field, the work done on the conductor by the electro-magnetic forces is equal to the product of the strength of the current into the number of lines of force which it cuts during its motion. Hence we arrive at the following general law, for determining the mechanical...
Stran 57 - Its magnitude is given by the product of one of the forces, and the perpendicular distance between the forces and its sense is clockwise or counterclockwise.
Stran 39 - M/a (3.21), therefore the potential at an external point at a distance r from the centre is given by V = Mjr.
Stran 136 - ... the product of the mass M and the square of the velocity) is at each instant equal to the actual work that has been done by gravity.
