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?

Answer 1

The correct answer should be elastic.

Answer 2

Answer: elastic potential energy

Step-by-step explanation:

The form of energy stored in the string of the bow is elastic potential energy. Elastic potential energy is the energy stored in an elastic object (such as the string of a bow) when the object is compressed/stretched by a certain amount x with respect to its natural length. The elastic potential energy stored in the object is given by

`U=(1)/(2)kx^2`

where k is the spring constant of the elastic string, and x is the compression/stretching.
