In the context of energy, what type of energy is stored for later use?
A
Radiant energy
B
Kinetic energy
C
Thermal energy
D
Potential energy
Verified step by step guidance1
Understand the concept of potential energy: Potential energy is the energy stored in an object due to its position or configuration. It is energy that has the potential to do work in the future.
Differentiate between types of energy: Radiant energy is energy carried by electromagnetic waves, kinetic energy is the energy of motion, and thermal energy is related to the temperature of an object.
Identify the characteristics of potential energy: Potential energy is often associated with forces such as gravity or elasticity. For example, a rock at the top of a hill or a compressed spring has potential energy.
Recognize examples of potential energy: Common examples include gravitational potential energy (e.g., an object held at a height) and elastic potential energy (e.g., a stretched rubber band).
Conclude that potential energy is the type of energy stored for later use, as it can be converted into other forms of energy, such as kinetic energy, when the conditions change (e.g., the rock falls or the spring releases).
