This is a form of potential energy:
boiling water.
a water wheel in motion.
electromagnetic radiation.
food.
The correct answer and explanation is:
Correct Answer: Food
Explanation:
Potential energy is the stored energy an object or substance has because of its position, condition, or composition. It is energy that has the potential to do work but is not currently being used. There are several forms of potential energy, such as gravitational potential energy, elastic potential energy, and chemical potential energy.
Food is a form of chemical potential energy. It contains energy stored within the chemical bonds of molecules such as carbohydrates, fats, and proteins. When a living organism consumes food, the body breaks down these molecules during digestion and metabolism. This process releases the stored energy, which the body then uses to perform functions like movement, growth, and maintaining body temperature.
The other options listed are not examples of potential energy:
- Boiling water is an example of thermal energy, which is a type of kinetic energy because it results from the movement of molecules.
- A water wheel in motion also represents kinetic energy, as it involves moving parts doing work, typically converting the kinetic energy of flowing water into mechanical energy.
- Electromagnetic radiation includes visible light, radio waves, and X-rays, and is a form of kinetic energy carried by photons in motion.
In contrast, food does not move or radiate energy in its natural state. It holds energy within its chemical structure until it is broken down. This characteristic makes food a classic and important example of potential energy. It is essential for all life forms because it provides the energy required for biological processes. When humans or animals eat food, their bodies unlock this stored potential energy and convert it into usable forms like ATP, which powers cells.
Thus, among the given choices, food is the only one that clearly represents potential energy.
