Solutions for "unit of work crossword clue" by Letter Count
3 Letters
ERG: A unit of energy or work in the CGS (centimetre-gram-second) system of units, equal to 10-7 joules.
5 Letters
JOULE: The standard unit of energy or work in the International System of Units (SI). One Joule is the energy expended when a force of one Newton moves an object one meter in the direction of the force.
7 Letters
CALORIE: A unit of energy, often associated with heat. One calorie is approximately the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
More About "unit of work crossword clue"
The concept of a "unit of work" is fundamental in physics and frequently appears in crosswords due to its precise definitions and distinct names. Work, in a scientific context, is performed when a force acts upon an object to cause a displacement. It's closely related to energy, as work is essentially the transfer of energy. Understanding these units not only helps in solving puzzles but also provides a deeper insight into basic scientific principles.
While the Joule is the internationally recognized SI unit, older systems like the CGS system still feature prominently in some fields and, consequently, in crosswords. The Erg is a classic example from the CGS system. The Calorie, though often thought of in terms of food energy, is also a valid unit of energy/work, particularly in thermodynamics and chemistry contexts. Recognising these different units and their contexts is key to tackling such clues effectively.
Tips For Your Next Puzzle
- Consider the System: If the clue hints at a specific system (e.g., "CGS unit"), it narrows down your options significantly (e.g., ERG).
- Check Letter Count: Immediately compare the available spaces in your puzzle grid with common unit names like ERG (3), JOULE (5), or CALORIE (7).
- Think Beyond Physics: While most "unit of work" clues point to physics, sometimes a lateral-thinking puzzle might refer to a 'unit of work' in a more metaphorical sense (e.g., a 'task' or 'assignment'). Always consider the puzzle's overall theme and difficulty.
- Use Cross-References: Leverage letters already filled in from intersecting words. These letters are your best guide to confirming or ruling out potential answers for "unit of work."

Frequently Asked Questions
What is a 'unit of work' in physics and crosswords?
In physics, a unit of work (or energy) quantifies the amount of energy transferred when a force causes displacement. Common examples include the Joule (SI unit) and the Erg (CGS unit). In crosswords, clues like 'unit of work' often point directly to these and similar scientific units, or sometimes older, less common ones.
Are 'work' and 'energy' units interchangeable?
Yes, fundamentally, work and energy are two sides of the same coin and are measured in the same units. Work is the process of energy transfer, while energy is the capacity to do work. Therefore, any unit of energy can also be considered a unit of work, and vice-versa.
How can I identify the correct 'unit of work' answer in a crossword?
Look at the number of letters required. Common answers are ERG (3 letters), JOULE (5 letters), and CALORIE (7 letters). The surrounding letters in the puzzle are also crucial. Sometimes, the clue might hint at a specific system (e.g., 'CGS unit of work' for ERG).
