Question

Suppose a candle is burning, and wind is blowing on one side of the flame.

Which principle explains why the flame bends toward the wind?


Archimedes’
Bernoulli’s
Newton’s
Pascal’s

Answer 1

Bernoulli's principle basically says that the higher the speed, the lower the pressure becomes. Since there's a lower pressure where the wind is blowing, that causes the flame to be pushed in the direction of the blowing.

You can test this yourself by getting a pingpong ball and blowing straight upwards. The ball will be continuously sucked back into the straight line, like this:
