... The gravitational constant G was measured in 1798 by Henry Cavendish. He used a balance with a quartz fiber. In order to twist a quartz fiber by an angle one has to exert a torque = c (this is very similar to the spring force F = kx). The constant c can be determined easily ...

... Note: This is a very weak field. In the presence of any significant field, it is easy to see why electric forces completely dominate gravitational forces in the sub-atomic world. 6. FE = q E = (50)(1.6 x 10 – 19)(1.92 x 105) = 1.536 x 10 – 12 N (The separation of the plates has nothing to do with th ...

... First of all, if the kinetic energies are the same, then when brought to rest, the non conservative work done on each would have to be the same based on work-energy principle. Also, since both have the same kinetic energies we have ½ m1v12 = ½ m2v22 … since the velocity is squared an increase in mas ...
