Question

When an arrow is released from a bow, potential energy changes into kinetic energy.
(A) True
(B) False
(C ) Ambiguous
(D) Data insufficient

Answer 1

Hint: Kinetic energy is the energy of motion. When the string is released, the P.E. is converted to K.E. in the direction of the arrow. The string pushes the arrow out and is the drive behind the motion. When an arrow is pulled back by a bow, there will be a strain on the bow and arrow. This P.E. is here converted into K.E. when the bowstring is released.

Complete answer:
When an arrow is pulled back by a bow, there will be a strain on the bow and arrow. This P.E. is here converted into K.E. when the bowstring is released.
Kinetic energy is the energy of motion. When the string is released, the P.E. is converted to K.E. in movement of the arrow. The string pushes the arrow out and is the drive behind the motion.
A bow with its string stretched, possesses P.E. on account of a change in its shape. To shoot an arrow, the string is released. The potential energy of the bow is changed into kinetic energy of the arrow.

The bow stores mechanical P.E. when it's pulled back. Each bow is distinct, including the draw weight placed on the bow by the person.
As the arrow weight is increased, the bow is in a position to transfer a better percentage of its stored energy (potential energy) into the arrow. Here the bow’s energy is converted into the end of the arrow against the string while pulling it back. On releasing the string by the shooter, the arrow moves forward with the elastic force of the bow. Here the elastic P.E of the bow is converted to the kinetic energy of the arrow.

While shooting an arrow from a bow a work is done on the bow by the shooter's arm to bend the bow and thus produce P.E. The release of the bow converts the P.E. of the bent bow into the K.E. of the flying arrow.
When the string of a bow and arrow is changed from equilibrium, the elastic P.E. within the bow is converted to K.E. of the arrow when the string is released.

So, the correct answer is “Option A”.

Note:
While shooting using an arrow a work is done on the bow by the shooter's arm and thus produce P.E. The release of the bow converts the P.E. of the bent bow into the K.E. of the flying arrow. When the string of a bow and arrow is pulled from equilibrium, the elastic P.E. within the bow is changed to K.E. of the arrow when the string is released.
