Question

select all the following that are examples of potential energy (stored energy).
slice of bread
speaker blaring music
book fallling from a table
boiling water
lifting a box
rock on a hill
battery
stretched spring

Explanation:

• Slice of bread: Contains chemical potential energy (stored in chemical bonds).
• Speaker blaring music: Produces sound energy (kinetic, not stored).
• Book falling from a table: Has kinetic energy during fall (not stored).
• Boiling water: Has thermal (kinetic) energy (not stored).
• Lifting a box: Increases gravitational potential energy (stored due to height).
• Rock on a hill: Has gravitational potential energy (stored due to height).
• Battery: Stores chemical potential energy.
• Stretched spring: Has elastic potential energy (stored due to deformation).

Answer:

• Slice of bread
• Lifting a box
• Rock on a hill
• Battery
• Stretched spring
