Question

potential energy
energy that is stored inside of an object due to its position
chemical | elastic | gravitational | nuclear
examples | examples | examples | examples

Explanation:

The problem is about potential energy and its types (chemical, elastic, gravitational, nuclear) with examples to be filled. This falls under Physics (a subfield of Natural Science) as it deals with energy concepts in physics. To solve, we recall examples for each type:

• Chemical Potential Energy: Energy stored in chemical bonds (e.g., batteries, food, gasoline).
• Elastic Potential Energy: Energy stored in stretched/compressed elastic objects (e.g., stretched rubber band, compressed spring).
• Gravitational Potential Energy: Energy due to height/position in a gravitational field (e.g., a book on a shelf, a roller coaster at the top of a hill).
• Nuclear Potential Energy: Energy stored in atomic nuclei (e.g., nuclear fission in power plants, fusion in the sun).

Answer:

Chemical Potential Energy Examples: Batteries, food (like a candy bar), gasoline (stored chemical energy for fuel).

Elastic Potential Energy Examples: Stretched rubber band, compressed spring (in a toy or a pogo stick), a drawn bow (archery bow).

Gravitational Potential Energy Examples: A book placed on a high shelf, a roller coaster at the peak of a track, a rock held above the ground.

Nuclear Potential Energy Examples: Nuclear power plants (using fission of uranium), the sun (fusion of hydrogen into helium), a nuclear bomb (fission/fusion reactions).
