This is a list of common physical constants and variables, and their notations. Note that bold text indicates that the quantity is a vector.
Symbols representing physical quantities, units, mathematical operations and relationships, astronomical bodies, constellations, and the Greek alphabet.
In physics, we use variables to represent physical quantities such as distance, time, mass, and velocity. Understanding and mastering variables is critical to solving physics problems, as variables are the building blocks of equations and the means by which we describe the physical world.
Frequently used equations in physics. Appropriate for secondary school students and higher. Mostly algebra based, some trig, some calculus, some fancy calculus.
Learn the definitions and units of displacement, velocity, acceleration, and force with animations and examples. See how to visualize and compare these physics variables and their changes over time.
The horizontal axis, or x-axis, shows the independent variable, which is the variable that is controlled or manipulated. The vertical axis, or y -axis, shows the dependent variable , the non-manipulated variable that changes with (or is dependent on) the value of the independent variable.
Variables are symbols used to represent quantities in mathematical expressions and equations. They are essential in physics as they allow us to generalize relationships between different physical quantities, making it easier to analyze and solve problems.
