... Two identical cars with really good bearings and solid tires roll on a very smooth, hard track (without friction). They start from rest and coast downhill, ending at the same height. How do their speeds compare at the end? a. 1 is going b. 1 is going c. 1 is going d. 1 is going e. 1 is going ...

THERMAL ENERGY AND OTHER TYPES OF INTERNAL ENERGY
... One may include into system the “adjacent objects affected by friction” and make the friction an internal non-conservative force of system. Then, the expression (3) would tell that net work provided by all external forces (friction is not any more external) goes to change the mechanical and thermal ...

Notes on Energy
... conservation of energy: as the rock falls, it accelerates and gains kinetic energy, but at the same time it loses exactly the same amount of potential energy, thus keeping the total energy (0 J, in this particular case) constant throughout! Recall that other forms of energy (thermal, chemical, elect ...

... • The potential energy stored in the plates is equivalent to the work done to charge the plates. This work is usually done by a battery • As charge is added to the plates, it takes increasingly more work to add additional charge because of electron repulsion ...
