KINETIC ENERGY

Woah, you wanna shoot one of these?  Okay, let's make sure your kinetic energy is high enough - otherwise, things might not end too well.

AN EXAMPLE

Let's say that your bow shoots a 350 grain arrow at 300 feet per second.  Knowing this, we can calculate it's kinetic energy like so:

KE = (mv^2)/456,240

KE = ((350)(300^2))/450,240

KE = 31,500,000/450,240

With all of this, we know that the kinetic energy is:

KE = 69.96 ft. lbs.

Or too much math.

Try using our calculator above.  It's easier.

CALCULATING KINETIC ENERGY

Power.  You want all the power.  But how do you get it?  Two words - Kinetic Energy (KE).  It's not too hard.  Kinetic Energy is all about the mass and the speed of an arrow.  Use those two variables to calculate your kinetic energy output - aka how much destruction your arrow can reign.  The formula to calculate KE is KE=(mv^2)/450,240, where "m" is the mass of the arrow (in grains), and "v" is the velocity of the arrow (in feet per second (fps)).
