713:"In the mathematical treatment of the exact sciences, mathematical quantities are assigned symbolic variables, such as 't' for time, 'x, y, z' for position coordinates, 'm' for mass, and so on. Calculus is the study of the rates at which some of these variables change relative to the others. In the course of expressing a law, equations arise which contain both the variables themselves, and their rates of change, and it is these that are called 'differential equations.' The task that the subject of Differential Equations sets itself is broadly to understand the meaning of a differential equation in terms of the geometry that underlies it, and to discover, if possible, simpler equations with fewer of those rates of change (or 'derivatives', as they are called). In particular, if it possible, it is desired to obtain an equation with no rates of change (derivatives) at all."

This means that the ball's acceleration, which is a derivative of its velocity, depends on the velocity. Finding the velocity as a function of time involves solving a differential equation.

A differential equation is, quite frankly, a technical thing, and a non-specialist can't seriously hope to understand the whole business by reading a

I respectfully disagree based on how an introductory class on differential equation is often taught. Usually one starts by talking about ODEs and PDEs, Linear and Non-linear, Homogeneous and Non-homogeneous (which could be added). Also, linear PDEs like the diffusion equation, the wave equation, and

Not sure how you fixed the first example. It still does not fit the definition given. Since the formal definition you quote says "although at least one derivative must be present", just use that in a simplified definition: an equation where at least one derivative of an unknown function is present.

Just like ODE and PDE are defined with their own section, I think it would be appropriate to define Linear and Non-Linear equations in their own section. Right now the definition of a Linear DE is buried inside the definition of an ODE. But PDE can be linear too.
