Hmmm...in classical mechanics courses, that's a commonly used shorthand for "partial derivative with respect to time." That is,
x' is ∂x / ∂t
x'' is the second partial derivative of x with respect to time, and so on.

That notation is used to mean "Derivative of"
y' means the first derivative of the whatever function y is.
y'' means the second derivative, etc.
The derivative is a calculus based concept.

Usually you use one apostrophe, so like y'. Usually it signifies a variable related to the original y.

it means the derivative
y' means the first derivative of y, y'' means the second derivative and so on

you are finding first, second and third derivatives. Which are finding rates of change on rates of change.
example: y' might find the speed of an item
then y'' would find acceleration (change in speed)
