a measurement of something in a particular direction, especially its height, length, or width: dimensions of Please specify the dimensions (= the height, length and width) of the room. a building of vast dimensions (= size) B2 [ C ] a part or feature or way of considering something: His personality has several dimensions.
In mathematics, the dimension of an object is, roughly speaking, the number of degrees of freedom of a point that moves on this object. In other words, the dimension is the number of independent parameters or coordinates that are needed for defining the position of a point that is constrained to be on the object.
The meaning of DIMENSION is measure in one direction; specifically : one of three coordinates determining a position in space or four coordinates determining a position in space and time. How to use dimension in a sentence.
Learn about the units and dimensions of physical quantities, the dimensional formula, the SI system of units, and the dimensional analysis. Find examples, definitions, formulas, and applications of units and dimensions in physics.
- It is an expression that relates derived quantities to fundamental quantities. But it is not related to the magnitude of the derived quantity.
- We know that, F = ma —– (1) Mass is a fundamental quantity, but acceleration is a derived quantity and can be represented in terms of fundamental...
- Suppose I have the following equation, F = E a .V b . Tc Where, F = Force; E = Energy; V = Velocity; M = Mass We need to find the value of a, b...
- The standard quantity with which a physical quantity of the same kind is compared is called a unit.
- This is because mass, length and time are independent of each other. All the other quantities in mechanics can be expressed in terms of mass, lengt...
- Significant figures are those digits in a number known with certainty plus one more uncertain number.
- The dimensions of a physical quantity are the powers to which the fundamental quantities are raised to represent that physical quantity.
Dimension definition: a property of space; extension in a given direction. See examples of DIMENSION used in a sentence.
A dimension is the measurement of something in physical space. You might give the painters every dimension of the rooms you want painted, including depth, height, and width. In addition to physical objects, dimension can describe something less tangible, such as the magnitude or extent of something.
