... T = 2(m/k)½ period T depends on mass m and force constant k. The order will not change the final velocity, since it only depends on the total mass at the end. Fg = GMm/r2, where M and r are doubled Fg = ½ as much (250 N). vav = d/t = (8 m – 2 m)/1 s = 6 m/s Thermal equilibrium means that the te ...

... • Just knowing the internal energy U of a system with a constant volume and temperature is not enough to tell us what the equilibrium configuration will be. • There could be many macrostates with the same U. That is why just minimizing U (or H) is not good enough, we have to minimize A = U TS or G = ...

... Is energy conserved? • A closed system is a group of objects that transfer energy only to one another. Energy is conserved in all closed systems. • The law of conservation of energy states that energy cannot be created or destroyed. It can only change forms. • All of the different forms of energy in ...

... you build muscles which increases your resting metabolic rate (RMR). A typical out–of-shape male has a RMR of about 70 watts, meaning 70 joules per second burned by just breathing, digesting, thinking. (70 W is about 1400 Cal/day). By exercising regularly, that RMR can be raised to 90 watts (1860 Ca ...

... isn't the equation E = KE + PE + thermal energy (instead of Q)? I'm going to write it that way because I think it will be easier for the students, and easier for me to explain. In this equation it seems to me that we're looking at a state of energy rather than a change of energy. If we are intereste ...
