Physical quantities can have dimensions, which represent how they are measured or expressed in terms of fundamental units like length, mass, time, etc. These dimensions help in defining and comparing different physical quantities. For example, the dimension of speed is [Length] / [Time] as it is defined as the distance traveled per unit time.
In physics, dimensions refer to the physical quantities such as length, time, and mass that are used to describe the properties of objects and phenomena. These dimensions are fundamental in defining and measuring various physical quantities. The dimensions of a physical quantity help in understanding how it relates to other quantities and how it can be expressed in terms of basic units.
Size is a measurable quantity that represents the dimensions or extent of an object or space in physical terms. It is typically measured using standard units such as length, width, height, volume, or area.
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
Yes, a dimensionless quantity is a quantity that does not have any physical dimensions or units. It is a pure number or ratio that represents a comparison between two quantities. Examples of dimensionless quantities include angles, ratios, and pure numbers like pi.
The dimensional formula of a physical quantity represents how it is composed of fundamental dimensions like length, mass, and time. For example, the dimensional formula of velocity is [LT^-1] where L represents length and T represents time. The dimension of a physical quantity refers to the type of fundamental dimension it represents, like length, mass, or time.
No. The dimensions are: Mass, Length, Time, and Charge. They transcend the systems of units. For example, speed will always have the dimensions of (Length)/(Time), regardless of the system of units.
The 'physical dimensions' of force are [ mass x length/time2 ].

A standard use for a measurement of a physical quantity is called the unit of that physical quantity

Yes, it is a physical quantity (Fundamental)

In physics, a dimension refers to a measurable extent of a physical quantity, such as length, mass, time, or temperature. Dimensions provide the framework for describing and understanding the physical world, and different physical quantities are often described using combinations of these fundamental dimensions.
Such a physical quantity is a vector.
[mass] [length2] / [time2] =[ mass-length/time2 ] x [length] =[force] x [length] = work or energy
