A
Water rushing over a water fall.
B
A glucose molecule.
C
A spring being released and expanding rapidly.
D
An ant foraging (moving around) for food.
Verified step by step guidance1
Understand the concept of potential energy: Potential energy is the stored energy in an object or system due to its position or arrangement. It has the potential to do work in the future.
Identify the examples given: Water rushing over a waterfall, a glucose molecule, a spring being released, and an ant foraging for food.
Analyze each example: Water rushing over a waterfall and a spring being released involve kinetic energy, which is the energy of motion. An ant foraging for food also involves kinetic energy as it is moving.
Consider the glucose molecule: A glucose molecule stores energy in its chemical bonds, which can be released during metabolic processes. This stored energy is an example of potential energy.
Conclude that the glucose molecule is the correct example of potential energy, as it contains stored energy that can be utilized by the body.
