WebForce times distance by definition, is work. And 1/2 mv squared, I said this is called kinetic energy. And so, by definition, kinetic energy is the amount of work-- and I mean this is the definition right here. It's the amount of work you need to put into an object or apply to an object to get it from rest to its current velocity. WebJul 30, 2003 · Energy is the u = 0, v = 0 part of this thing, i.e. T^00. However this is really an energy density, i.e. 'energy per unit volume. This is the mathematic object that appears as the source of gravity in Einstein's field equations. One can define a "mass tensor" by dividing T^uv by c^2. I.e. M^uv = T^uv/c^2. top dallas restaurants uptown

When the treadmill replaces the road surface, two things happen: the belt has lower inertia so the runners body is not so decelerated by the impact; and the belt stretches and stores some of the energy elastically. This is where the energy saving comes from - what DMcKee called "easy on the knees".
