What is the dimensions definition in physics and how does it relate to the fundamental properties of physical quantities?
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.
What is dimensions of physical quantity?
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.
Is size a quantity?
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.
Can a quantity have unit and still be diamensionless?
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.
Can a quantity be dimensionless and have no 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.
Does a quantity have different dimensions in different systems of units?
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.
What quantity is force made up of?
The 'physical dimensions' of force are [ mass x length/time2 ].

What the definition of base quantities?
all physical quantity is called base quantity
What are all of the dimensions?
All physical quantities are combinations of one or more of the dimensions of length, mass, time, and electric charge.

What is meant by unit of physical quantity?
A standard use for a measurement of a physical quantity is called the unit of that physical quantity

Is distance a physical quantity?
Yes, it is a physical quantity (Fundamental)

How is time measurable by physical devices if it is not a physical quantity?
Well, some physical devices don't work at all.
