∆
The symbol ∆, often referred to as "delta," is used in various contexts to represent change or difference. It can be used in mathematics, science, and other fields to indicate a change in a variable or a difference between two values. For example, if you have two numbers, A and B, then ∆A could represent the change in A, which is usually calculated as ∆A = A2 - A1, where A2 is the new value and A1 is the initial value. In physics, delta (∆) is often used to represent a change in a physical quantity.
It's a versatile symbol that signifies a transition or alteration from one state to another, making it a valuable concept in many disciplines.

geometrix [#4]On AP Physics problems, acceleration is denoted as ∆v.
That's because ∆v = change in v = acceleration
