OK I have a few stupid questions, some of which I need to confirm answers too.
1. How does a car increase it's speed? When a driver accelerates, more fuel is injected so the explosion size increases, and the piston moves with more force downwards at a greater speed. Is that true?
So the intake of gasoline by the cylinder depends on how hard you press on the acceleration?
So a car's speed depends on the movement of the piston, which in turn depends on how much fuel is injected?
2. If what I said above is true, then how long does it take the piston to move from the bottom of the cylinder to the top when the car is at its lowest speed? How long does it take to move from the top to the bottom when the car is at its lowest speed?
How long does the piston take to move from the bottom to the top when the car is at its highest speed? From the top to the bottom?
3. What is the best way to reduce friction between two pieces of wood so that the friction between the two pieces of wood be at its lowest?
4. Is there anyway to block out the magnetic field of a magnet? What is it?
Thanks a lot.
And sorry mods if I posted this in the wrong section, I wasn't sure which section to post this in.
