Car converts chemical energy to mechanical energy in the engine, by combining carbon in the fuel with oxygen from the air to create carbon dioxide that goes out of the exhaust (hydrogen in the fuel is also combined with oxygen to create water vapour).
The heat generated by these chemical processes drives the piston, the crankshaft and the car.

The mechanical energy is transferred into kinetic energy as the car moves forward, and into potential energy if the car climbs a hill.

When the time comes to stop, the kinetic energy of the car is converted into heat by friction in the brakes.

as stated before, laughing releases your body's "feel good" chemicals, and on a related note, negative stress can cause your body to release chemicals that weaken your immune system which makes you more likely to contract a disease. luckily, laughter reduces negative stress and prevents those chemicals from being released.

In this excerpt from "quality" by john galsworthy, which two parts clearly indicate the literary point of view of the essay? that tenement had a certain quiet distinction; there was no sign upon its face that he made for any of the royal family—merely his own german name of gessler brothers; and in the window a few pairs of boots. i remember that it always troubled me to account for those unvarying boots in the window, for he made only what was ordered, reaching nothing down, and it seemed so inconceivable that what he made could ever have failed to fit. had he bought them to put there? that, too, seemed inconceivable. he would never have tolerated in his house leather on which he had not worked himself. besides, they were too beautiful—the pair of pumps, so inexpressibly slim, the patent leathers with cloth tops, making water come into one's mouth, the tall brown riding boots with marvellous sooty glow, as if, though new, they had been worn a hundred years. those pairs could only have been made by one who saw before him the soul of boot—so truly were they prototypes incarnating the very spirit of all foot-gear. these thoughts, of course, came to me later, though even when i was promoted to him, at the age of perhaps fourteen, some inkling haunted me of the dignity of himself and brother. for to make boots—such boots as he made—seemed to me then, and still seems to me, mysterious and wonderful.
