acceleration
(noun)
the change of velocity with respect to time (can include deceleration or changing direction)
Examples of acceleration in the following topics:
-
Higher Derivatives
- The second derivative of $x$ is the derivative of $x'(t)$, the velocity, and by definition is the object's acceleration.
- Acceleration is the time-rate of change of velocity, and the second-order rate of change of position.
-
Planetary Motion According to Kepler and Newton
- Newton derived his theory of the acceleration of a planet from Kepler's first and second laws.
- In addition, the magnitude of the acceleration is inversely proportional to the square of its distance from the Sun.
- From this, Newton defined the force acting on a planet as the product of its mass and acceleration.

Physics and Engineering: Fluid Pressure and Force
- For fluids near the surface of the earth, the formula may be written as $p = \rho g h$, where $p$ is the pressure, $\rho$ is the density of the fluid, $g$ is the gravitational acceleration, and $h$ is the depth of the liquid in meters.
-
Calculus with Parametric Curves
- The acceleration can be written as follows with the double apostrophe signifying the second derivative:
-
Vectors in Three Dimensions
- Vectors play an important role in physics: velocity and acceleration of a moving object and forces acting on it are all described by vectors.
-
Differentiation and Rates of Change in the Natural and Social Sciences
- For example, in physics, the derivative of the displacement of a moving body with respect to time is the velocity of the body, and the derivative of velocity with respect to time is acceleration.
-
Vector-Valued Functions
- If we differentiate a second time, we will be left with acceleration:
-
Arc Length and Curvature
- Where $\kappa$ is the curvature and $\frac{dT}{ds}$ is the acceleration vector (the rate of change of the velocity vector over time).

Graphing on Computers and Calculators
- c) Three-dimensional graphing: While high-end graphing calculators can graph in 3-D, GraphCalc benefits from modern computers' memory, speed, and graphics acceleration.
