1
overall size, extent, or importance
How big, serious, or important something is.
Vzorec užití:
the magnitude of [something]
Častá chyba:
Learners sometimes use magnitude only for physical size and forget it is very common for non-physical things like problems, risks, or achievements. Another common mistake is to omit the preposition of, for example saying the magnitude the problem instead of the magnitude of the problem.
Synonyma
scale (Focuses on the overall size or level of something, especially when comparing things.)
|
extent (Stresses how far something reaches or how much it covers.)
|
seriousness (Emphasizes how severe or grave a situation is rather than its physical size.)
Antonyma
smallness (Direct opposite in terms of size or extent.)
|
insignificance (Opposite in terms of importance; suggests that something does not really matter.)
Kolokace

Příklady
- We underestimated the magnitude of the crisis until it began to affect every region of the country.
- The report makes clear the magnitude of the changes needed to reach our climate goals.
- Only later did she realize the true magnitude of her achievement.
- The sheer magnitude of the data breach shocked both customers and regulators.
- Historians still debate the magnitude of his influence on modern politics.
Učební příklady
- They did not understand the magnitude of the problem.

2
numerical size of a quantity
The number that shows how big a force, value, or other quantity is, without its direction or sign.
Vzorec užití:
the magnitude of [a force/value]; [number]-magnitude [measurement]
Častá chyba:
Learners sometimes mix up magnitude with direction when talking about vectors, or they confuse magnitude with sign in mathematics. In many technical contexts, magnitude refers only to how big something is, not where it points or whether it is positive or negative.
Synonyma
size (Everyday word; less precise and not limited to numerical or scientific contexts.)
|
absolute value (Specific mathematical term for the magnitude of a real number regardless of sign.)
Antonyma
zero (Represents the absence of magnitude; a quantity with zero magnitude has no size or strength.)

Příklady
- The magnitude of the force is 10 newtons, acting at an angle of 30 degrees.
- To find the magnitude of the vector, you take the square root of the sum of the squares of its components.
- The earthquake had a magnitude of 7.1 on the local scale.
- In this graph, the color shows the direction and the length shows the magnitude of the electric field.
- Even a small change in angle can greatly reduce the magnitude of the resulting acceleration.
Učební příklady
- We calculated the magnitude of the vector in class.
- The earthquake reached a magnitude of 6.5.
- This formula gives the magnitude of the force on the object.
- You can show the magnitude of a number with its absolute value.
- The diagram compares the magnitudes of the different signals.

brightness of a star on a scale
In astronomy, a number that shows how bright a star or planet is, where smaller numbers mean it is brighter.
Vzorec užití:
[apparent/absolute] magnitude of [a star/object]
Častá chyba:
Learners often think that a higher magnitude number means a brighter star, but in astronomy the scale is reversed, so smaller or negative magnitudes are brighter.
Synonyma
brightness (General word; magnitude is the specific measured brightness on an astronomical scale.)
Antonyma
faintness (Describes very low brightness, the opposite of being bright on the magnitude scale.)
Kolokace

Příklady
- The star has an apparent magnitude of 1.2, so it is easily visible to the naked eye.
- Astronomers use absolute magnitude to compare the true brightness of stars at a standard distance.
- As the comet approached the Sun, its magnitude decreased and it became much easier to see.
- Objects with a visual magnitude greater than 6 are usually too faint to see without a telescope.
- On this chart, lower magnitude values indicate brighter galaxies.
Učební příklady
- The star is very bright, with a low magnitude number.
- We learned how to find the apparent magnitude of a star.
- Absolute magnitude shows how bright a star really is.
- A star with magnitude 2 is brighter than a star with magnitude 5.
- The telescope lets us see objects with very high magnitude values.
