What does the symbol E represent in physical science?

In physical science, the symbol "E" is conventionally used to represent energy. Energy is a fundamental concept that refers to the capacity to do work or produce change. It can exist in various forms, such as kinetic energy (energy of motion), potential energy (stored energy based on position), thermal energy (heat), and many others.

This usage of "E" aligns with established conventions in the field, such as in equations related to energy principles—like Einstein's famous equation E=mc², which demonstrates the relationship between energy (E) and mass (m). Understanding energy is essential across multiple scientific disciplines, as it plays a critical role in physical processes and systems.

In contrast, the other options represent different physical quantities that do not align with the symbol "E." Mass is typically denoted by "m," time by "t," and distance by "d." Recognizing these conventions is crucial for interpreting scientific formulas and understanding the relationships between different physical properties.
