Work and Kinetic Energy
... define kinetic energy, which is energy an object possesses because of its motion. In general, we can think of energy as the capacity that an object has for performing work. We shall see that the concepts of work and kinetic energy can be applied to the dynamics of a mechanical system without resortin ...

... Figure 4 shows a trolley running down a friction compensated runway. The trolley is connected to a hanging weight by means of a light inelastic string. A card of width 0.03 m is attached to the trolley. Light sources S and light detectors D are fixed at two positions A and B along the runway. Each l ...

Time, what is it? Dynamical Properties of Time
... For the purpose of constructing the rigorous and consistent theory taking into account the possible appearance of the physical properties of time, one should turn to dynamics. As was noted above, it is the dynamical principle that relates the evolution of a system in time to the action of the force ...

... higher that the tallest point, Mount Everest (8850 m). How long will it take the ball to return to Everest? SOLUTION: We want to find the period T. We know that v = 8000 m s-1. We also know that r = 6408850 m. Since v = 2r/T we have T = 2r/v T = 2(6408850)/8000 T = (5030 s)(1 h / 3600 s) = 1. ...
