While releasing the arrow from a stretched bow, the Potential Energy of the bow is converted into?

The correct answer is B, kinetic energy. A stretched bow stores elastic potential energy, and when the string is released that store becomes the kinetic energy of the flying arrow. Potential energy is the energy held by a body because of its position or its shape. Pulling the string changes the shape of the bow, so the work done by the archer is stored as elastic potential energy, the same kind of store found in a compressed spring or a wound watch spring. On release the bow springs back to its old shape and pushes the arrow forward, so the stored energy turns into energy of motion. A small part does escape as the twang of sound and as heat, but the main change is potential to kinetic. Option A is wrong because chemical energy is stored in the bonds of fuels and food, not in a bent bow. Option C is wrong because the sound is only a small loss, not the main conversion. Option D is wrong because heat is likewise a minor loss here. Exam tip: a stretched bow, a compressed spring and a drawn catapult all store elastic potential energy.
