Question 3 • Chemistry A.1 - F26 - Jacob Metsker

In which situations is elastic potential energy present? Check all that apply.

Answer
A
A bow is drawn back from its equilibrium position.
B
An arrow rests on a bow.
C
A spring toy dart gun is unloaded.
D
A spring toy dart gun is loaded with a dart.
E
A bungee cord is connected to a tall tower.
F
A bungee cord is stretched with a person at the end.

Explanation

Elastic potential energy is stored when an elastic object is deformed from its relaxed shape. Drawing back a bow bends it, loading the dart gun compresses its spring, and stretching the bungee cord deforms it, so each stores elastic potential energy. An arrow merely resting on a bow, an unloaded gun, and a cord that is only connected to a tower are not necessarily deformed.
