While discussing cylindrical coordinates, I start with polar coordinates, which already use r (or ρ) and θ (or φ), and then add one more value, z, for height. That small…
Spherical coordinates are three numbers used to specify the exact position of a point in three-dimensional space within a spherical coordinate system. In this system, the numbers are one radial…
The polar coordinate system is a way of locating points on a plane using polar coordinates (r,θ). The first coordinate r tells you how far the point is from a…
A coordinate plane is just a flat surface (like a piece of paper) where you can plot and find exact locations of points with the help of a 2D Cartesian…
A Cartesian coordinate system is a way to specify the exact position of a point using perpendicular reference lines called axes. René Descartes, a French mathematician and philosopher, laid the…
Imagine you are trying to describe the exact location of an object on a floor. You might say, "a little to the right, then go straight a bit," which is…
The principle of homogeneity of dimensions is a rule in dimensional analysis in physics to ensure the consistency of equations. For any law of physics to be valid, it must…
If you’ve ever looked at a physics equation and wondered, Is this even correct?, You’re already thinking in the direction of dimensional analysis. It is a quick checking method used…
In physics, base quantities make up all derived quantities. By studying dimensions and their dimensional formulas, you can see how derived quantities are built from base quantities. You can also…
