Detailed explanation-1: -When an arrow is released from a bow, potential energy changes into kinetic energy.
Detailed explanation-2: -When the string of a bow and arrow is pulled from equilibrium, the elastic potential energy in the bow is converted to kinetic energy of the arrow when the string is released.
Detailed explanation-3: -The other aspect of energy that the bow portrays is kinetic energy. Kinetic energy is the energy of motion. 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.
Detailed explanation-4: -A drawn bow possesses mechanical energy due to its stretched position (elastic potential energy). An object that possesses mechanical energy is able to do work.
Detailed explanation-5: -The data looks fairly linear with a slope of 0.548. This means that if I pulled back the string and used 100 Joules of work, about 54.8 Joules would go into the kinetic energy of the arrow.
