Question

An archer pulls back the string of a bow to release an arrow at a target. Which kind of potential energy is transformed to cause the motion of the arrow?

A.chemical
b.gravitational
c.elastic
d.magnetic

Answer 1

Elastic, it's not chemical, there is no chemical reaction happening, gravational would be like dropping a rock, and there are no magnets when it comes to archery, leaving only elastic, which makes sense because you have a sense string releasing energy and it becomes projectile motion.

Answer 2

Elastic Potential Energy because the elasticity in the string stores up the energy.
