607,705 | On Wikipedia, it is stated that the Biot-Savart law is a formula used for determining the magnetic field pseudovector **B**(**r**) at a position vector **r** due to a current-carrying wire, but that the formula only works for constant/steady electric currents. Wikipedia then states the law:

] | As you said, "A slow draw stores energy in the bow that is then released quickly."
The speed of the string, and therefore the speed of the arrow, is much faster than the archer's arm can move. The arrow's kinetic energy is proportional to the square of its speed.
Greater speed translates to greater range.
Greater en... | When an archer pulls back on a bow, it is the bow that bends. The energy that is able to be stored and released depends a lot on by the elasticity and tensile strength of the bow, and also the size of the bow, as that determines how much advantage you can get from leverage.
Leverage I would say is one of the main issu... |
