The moment the arrow is released, potential energy (elastic energy in the bow) is converted into kinetic energy.
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.
A bow and arrow use mechanical energy, which is the energy stored in the bow when it is drawn back. When the arrow is released, this stored energy is transferred to the arrow as kinetic energy, propelling it forward.
There is no energy there until the bow string is stretched. The human arm pulling back on the bow string is the source of the energy which is stored mechanically in the flexure of the bow and converted into the kinetic energy of the arrows flight when the archer releases the arrow.
The arrow gets its kinetic energy from the potential energy stored in the bent bowstring. As the bowstring is released, the potential energy is converted into kinetic energy, propelling the arrow forward.
The energy conversion that takes place as an arrow is shot from a bow is from potential energy stored in the bent bow to kinetic energy of the arrow in motion. When the bowstring is released, the potential energy is rapidly transformed into kinetic energy as the arrow accelerates forward.
When an archer pulls the string on the bow, mechanical energy from the archer's muscles is transformed into potential energy stored in the bent bow. When the archer releases the bow, the potential energy in the bow is converted back into kinetic energy of the arrow as it is propelled forward.
When an arrow is shot from a bow, the potential energy stored in the bow's limbs is converted into kinetic energy as the arrow is released. According to the law of conservation of energy, energy cannot be created or destroyed, only transformed from one form to another. In this case, the total energy of the system (bow and arrow) remains constant, with potential energy decreasing as kinetic energy increases.
At the moment of release, all the energy stored in the bow (100J) is converted to the kinetic energy of the arrow. So, the kinetic energy of the arrow at that moment is 100J.
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.
The energy transformation that occurs when an arrow is released from its bow is potential energy being converted into kinetic energy. The potential energy stored in the stretched bowstring is transferred to the arrow as it is released, causing it to accelerate and move forward.
A bow is considered an elastic form of energy because when it is drawn back, it stores potential energy in the form of elastic deformation of the bow and the bowstring. When the bowstring is released, this potential energy is converted into kinetic energy in the arrow, which then propels the arrow forward.
