Right after you let go of the string and send it flying.
Yes. The arrow has this energy and had potential energy when drawn back and to the moment of release.
Kinetic Energy = 1/2*mass*velocity squared
KE = 1/2mV2

The potential energy of the mass of the sky diver is transformed into kinetic energy during the free fall. The kinetic energy of the free fall is transformed into kinetic energy and heat of the air when the parachute is deployed.
40 Joules. This would also mean that the ideal included zero mass or elasticity in the "string" of the bow, friction is non-existent, and it is accomplished in a vacuum.
When you stretch a bow , the work done by you in stretching the bow is stored in the form of potential energy . This potential energy get converted in to kinetic energy of the bow when released.
You calculate the new kinetic energy, you calculate the old kinetic energy, then you subtract.
Yes, a flying arrow has kinetic energy. Kinetic energy is the energy an object possesses due to its motion, and since the arrow is in motion, it has kinetic energy. The amount of kinetic energy depends on the mass and velocity of the arrow.
no
I think you mean bow and arrow. In this case, when you pull back an arrow on a bow, you apply kinetic energy (the energy of motion) to the bow and arrow to give it potential energy (energy that can be turned into kinetic energy at a later time). Anyway, the laws of conservation of energy state that energy cannot be created or destroyed; therefore all energy in the world is only changed to other different forms. As I said above, your kinetic energy (coming from your body) applied action to the bow and arrow, making the kinetic energy change into potential energy. Of course, when you let go of the arrow, the potential energy changes back into kinetic energy, allowing to arrow to fly off.
It has, or possesses, Kinetic Energy: the Energy of Motion.
A heavy arrow will have more kinetic energy when shot from a compound bow compared to a light arrow. Kinetic energy is determined by both the mass and velocity of an object. Although a heavy arrow may have a lower initial velocity, its greater mass compensates and results in higher kinetic energy than a lighter arrow.
The kinetic energy of the arrow is dependent on its weight and the speed at which it is launched. if you use one bow to fire two different sized arrows, they will both have the SAME kinetic energy. a heavy arrow will shoot slower but hit harder while the light arrow will fly faster but wont impact as hard.
kinetic energy and spring/elastic energy
The moment the arrow is released, potential energy (elastic energy in the bow) is converted into kinetic energy.
The energy in the stretched bowstring is potential energy - specifically, elastic energy. This is converted into kinetic energy, when the arrow is released.
When you bend the bow, you are imparting kinetic energy from your pull into the bow as potential energy. When you release the string, you are imparting that potential energy into the arrow through the string.
the reason on how this is an example is when you let go of the arrow, the potential energy changes back into kinetic energy, allowing to arrow to fly off - Jaylin C
