In Science What Are The Three Variables?

Answer 1

It depends on the problem. Variables are defined as an unknown quantity that can change.

Perhaps you mean "dimension" which is a parameter or measure required to define the charateristics of an object. And depending on what object we are talking about they are fixed.

So for space-time there are four dimensions - the three orthogonal spatial directions (commonly labeled x, y and z) and time (labeled t). Or on the earth it is latitude and longitude and so on.

Or maybe the question is actually asking is what are the fundamental physical quantities and their "units". In the SI system (international standard of units) which all measurements reduce to and that is "MLT" - or Mass, Length and Temperature. But even though these are the most common there are in fact seven - time, distance, velocity, mass, momentum, energy, and weight.

I more inclined to think, at the level of the question, perhaps the question is asking for Length, Width & Height.

Do you have some further context to help us answer this question?

Answer 2

The three most common variables are length, weight, and time.
In the USA use the inch, pound, second system while most other countries use the metric system which is centimeter, gram, second system.

The USA has been attempting for some time now to convert to the metric system, so as to be consistent with the rest of the world, but progress in that direction is slow except in the field Of Science.

Answer 3

Control Variable this is the one that needs to be kept within the test to keep it fair.

Answer 4

i assume that you mean the position coordinates in the three dimensional space

so the variables are the position coordinates in the three dimensional space ( horizontal, vertical , and up/down )

Answer 5

There are far more than 3. Time, space( 3 dimensions) temperature, pressure & volume are some of them. There are many others.
