You’ve probably heard the expression, straight as an arrow. But, do arrows really travel in a straight line? We will be exploring this through this project.
It takes energy to move an object. For example, when you throw a ball you are using your energy and transferring it to the ball. The distance that the ball travels depends on your aim and strength. The trajectory of the ball – path it follows – depends on your technique. The bow and arrow work in the same way. You use energy to pull back the bow string. When you release the string, energy is transferred from the string to the arrow which flies through the air. The distance that the arrow travels and its trajectory will depend on your aim, strength, and technique. You can improve these with practice and a knowledge of basic engineering principles.
Shooting an arrow requires different types of energy. The archer supplies the initial energy by drawing the bow. The limbs of the bow provide elastic potential energy as they are pulled back by the bow string. The energy that the arrow has is called kinetic energy – the energy of motion.
There is another consideration involved in shooting an arrow: the “archer’s paradox.” The term archer’s paradox refers to the fact that an arrow must bend around the bow and flexes in a wave-like pattern until it hits the target.
