Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Kinetic or potential? A man shooting an arrow from his bow.
A
Kinetic
B
Potential
Explanation: 

Detailed explanation-1: -Before shooting, the bow has elastic potential energy due to its stretched position. This elastic potential energy of the bow is converted into kinetic energy when the arrow is shot from the bow.

Detailed explanation-2: -When the string is released, the potential energy is converted to kinetic energy in movement of the arrow. The string pushes the arrow out and is the driving force behind the motion. The harder an archer works to pull the bow, the greater the potential energy, and thus the greater the kinetic energy of the arrow.

Detailed explanation-3: -When an arrow is drawn back by a bow, the work done by us in stretching the bowstring gets stored at potential energy in the bow. This potential energy of bow is transformed into kinetic energy when the bowstring is released and this gives kinetic energy to the arrow.

Detailed explanation-4: -When an arrow is released from a bow, potential energy changes into kinetic energy.

Detailed explanation-5: -Projectile motion is movement of an object in a curved path toward the ground because it has both a horizontal force and the downward force of gravity acting on it. Examples of objects that have projectile motion include arrows and cannon balls.
