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

A bow is drawn back from its equilibrium position.

An arrow rests on a bow.

O A spring toy dart gun is unloaded.

A spring toy dart gun is loaded with a dart.

A bungee cord is connected to a tall tower.

A bungee cord is stretched with a person at the end.

A bow is drawn back from its equilibrium position.

A spring toy dart gun is loaded with a dart.

A bungee cord is stretched with a person at the end.

Explanation:

All of these examples have to do with the elastic object being stretched but not in motion, therefore they have stored energy, or potential energy.

A bow is drawn back from its equilibrium position.

A spring toy dart gun is loaded with a dart.

A bungee cord is connected to a tall tower.

A bungee cord is stretched with a person at the end.

Explanation:

Potential energy is defined as the energy a material posesses by it viture of position. elastic potential potential energy is a special case of potential energy which is defined as the potential energy that is stored in material that are elastic. Elastic is connected with stretching and so looking at the options, option 2 and 4 are out of the lists
