Polar Coordinate System | Coordinates, Plot, Convert, Graph
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…
What is a Coordinate Plane? Definition, Quadrants & Graphing
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…
Cartesian Coordinate System | Definition, Types & Examples
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…
What is a Coordinate System? Definition and Its Types
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…
Principle of Homogeneity of Dimensions with Uses & Examples
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…
Dimensional Analysis: Definition, Uses, and Limitations
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…
Dimensions of Physical Quantity (+29 Examples)
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…
Accuracy and Precision: Definition, Examples, and Differences
Accuracy and precision are two different but closely related concepts used to evaluate the quality of measurements. You might be baking a cake, measuring the dimensions of your room, or…
How to Calculate Uncertainty in Physics (Step-by-Step)
I wrote this article for students who are starting out with A-level or introductory physics. For this reason, while explaining how to calculate uncertainty, I’ll consider only the uncertainty arising…
