Gravity is considered constant, and air resistance may be modeled as proportional to the ball's velocity.

This means that the ball's acceleration, which is a derivative of its velocity, depends on the velocity and the velocity depends on time.

Finding the velocity as a function of time involves solving a differential equation and verifying its validity. Types[ edit ] Differential equations can be divided into several types.

Apart from describing the properties of the equation itself, these classes of differential equations can help inform the choice of approach to a solution.

This list is far from exhaustive; there are many other properties and subclasses of differential equations which can be very useful in specific contexts. Ordinary differential equations[ edit ] Main articles: Ordinary differential equation and Linear differential equation An ordinary differential equation ODE is an equation containing an unknown function of one real or complex variable x, its derivatives, and some given functions of x.

The unknown function is generally represented by a variable often denoted y , which, therefore, depends on x.

Thus x is often called the independent variable of the equation. The term "ordinary" is used in contrast with the term partial differential equation , which may be with respect to more than one independent variable.

Linear differential equations are the differential equations that are linear in the unknown function and its derivatives. Their theory is well developed, and, in many cases, one may express their solutions in terms of integrals.

Most ODEs that are encountered in physics are linear, and, therefore, most special functions may be defined as solutions of linear differential equations see Holonomic function. As, in general, the solutions of a differential equation cannot be expressed by a closed-form expression , numerical methods are commonly used for solving differential equations on a computer.

Partial differential equations[ edit ] Main article: Partial differential equation A partial differential equation PDE is a differential equation that contains unknown multivariable functions and their partial derivatives. This is in contrast to ordinary differential equations , which deal with functions of a single variable and their derivatives.

PDEs are used to formulate problems involving functions of several variables, and are either solved in closed form, or used to create a relevant computer model. PDEs can be used to describe a wide variety of phenomena in nature such as sound , heat , electrostatics , electrodynamics , fluid flow , elasticity , or quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs.

Just as ordinary differential equations often model one-dimensional dynamical systems , partial differential equations often model multidimensional systems. PDEs find their generalisation in stochastic partial differential equations.
