8-1 Newton`s Law of Universal Gravitation
... In this case, there are no non-conservative forces acting, and in the initial state the kinetic energy is zero because both objects are at rest. This gives U i = U f + K f . The final kinetic energy represents the kinetic energy of the system, the sum of the kinetic energies of the two objects. Let’ ...

... the Earth’s surface, whether falling or stationary, exerts a gravitational pull on the Earth, opposite to the pull of the Earth on the body, but the result cannot be measured. One test of the third law is provided by the motion of celestial bodies of comparable mass, like binary stars. We shall see ...

... This all seems straightforward, but conceptual difficulties arise when the speed or acceleration is not fixed. And they can’t both be constant, because constant (and nonzero) acceleration implies a changing speed. Suppose you drive along a country lane, speeding up on the straights, slowing for the ...
