The best description of energy is:
a. The ability to do work
Explanation:
1. Energy is defined as the capacity to do work or the ability to cause change. It is a fundamental concept in physics and plays a crucial role in various processes in the universe.
2. When energy is applied to an object, it can result in the object's movement, transformation, or other effects, demonstrating its capacity to do work.
3. For example, when a person lifts a heavy object, the energy used to lift it is transformed into gravitational potential energy. This transformation illustrates how energy enables work to be done on the object.
In summary, energy is best described as the ability to do work, highlighting its essential role in causing changes and transformations in the world around us.
