gradient gradient - the property possessed by a line or surface that departs from the horizontal; a five-degree gradient. slope. grade - the gradient of a slope or road or other surface; the road had a steep grade. rake, slant, pitch - degree of deviation from a horizontal plane; the roof had a steep pitch. precipitousness, steepness, abruptness - the property possessed by a slope that is very steep.

What is the concentration gradient? As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. <i>down the gradient</i>.

- You don't need differentiating at all. The gradient of the graph represents the force acting on the mass. First you need to make the graph linear, by making it a- 1/mass (on the X axis) vs acceleration ms-2 (on the Y axis).

- Geothermal gradient. Geothermal gradient is the rate of increasing temperature with respect to increasing depth in the Earth's interior. Away from tectonic plate boundaries, it is about 25 °C per km of depth (1 °F per 70 feet of depth) near the surface in most of the world.

Anatomy & Physiology Chapter 20 The pressure gradient of systemic circulation is calculated by subtracting the mean arterial pressure in the vena cava from that of arteries near the aorta. This blood pressure gradient is the driving force to move blood through the vasculature.

Color gradient Color gradient. In computer graphics, a color gradient (sometimes called a color ramp or color progression) specifies a range of position-dependent colors, usually used to fill a region. For example, many window managers allow the screen background to be specified as a gradient.

gradient 1 A rate of inclination; a slope. 2  An ascending or descending part; an incline. 3  Physics The rate at which a physical quantity, such as temperature or pressure, changes in response to changes in a given variable, especially distance.plural gradients). 1  A slope or incline. 2  A rate of inclination or declination of a slope. ( 3 calculus) Of a function y = f (x) or the graph of such a function, the rate of change of y with respect to x, that is, the amount by which y changes for a certain (often unit) change in x.

Origin of Wind Pressure gradient is just the difference in pressure between high and low pressure areas. The speed of the wind is directly proportional to the pressure gradient meaning that as the change in pressure increases (i.e. pressure gradient increases) the speed of the wind also increases at that location.

Gradient The gradient of H at a point is a vector pointing in the direction of the steepest slope or grade at that point. The steepness of the slope at that point is given by the magnitude of the gradient vector.The gradient can also be used to measure how a scalar field changes in other directions, rather than just the direction of greatest change, by taking a dot product. Suppose that the steepest slope on a hill is 40%.he steepness of the slope at that point is given by the magnitude of the gradient vector. The gradient can also be used to measure how a scalar field changes in other directions, rather than just the direction of greatest change, by taking a dot product. Suppose that the steepest slope on a hill is 40%.

- These notes correspond to Section 11.6 in Stewart and Section 2.6 in Marsden and Tromba. Directional Derivatives and the Gradient Vector. Previously, we de ned the gradient as the vector of all of the rst partial derivatives of a scalar-. valued function of several variables. Now, we will learn about how to use the gradient to measure. the rate of change of the function with respect to a change of its variables in any direction, as. opposed to a change in a single variable. This is extremely useful in applications in which the. minimum or maxmium value of a function is sought.

What is an example of concentration gradient? An example of concentration gradient is food dye diffusing in a glass of water. A concentration gradient is the change in concentration in a solution measured over the distance. Continue Reading. In the example, the concentration on the dye is found stronger where the dye is more vibrant. The solution that is more diluted is clear without traces of the dye.

Vector Calculus: Understanding the Gradient We know the definition of the gradient: a derivative for each variable of a function. The gradient symbol is usually an upside-down delta, and called “del” (this makes a bit of sense – delta indicates change in one variable, and the gradient is the change in for all variables).

Why Are Cells Powered by Proton Gradients? When enough protons have accumulated, the proton motive force powers the formation of ATP. So a gradient allows cells to save up protons as loose change, and that makes all the difference in the world — the difference between growth and no growth, life and no life.

gradient Popular Terms. Steepness of a slope (incline or decline), commonly measured in one of the three ways: (1) The angle (called the 'slope angle') the line, path, or surface makes with the ground or horizontal (called 'grade line') expressed in degrees or grads. For example, a 5 degree gradient.

Definitions &Translations The term is sometimes used to denote simply the magnitude of the gradient of the pressure field. Pressure gradient. In atmospheric sciences, the pressure gradient is a physical quantity that describes which direction and at what rate the pressure changes the most rapidly around a particular location. The pressure gradient is a dimensional quantity expressed in units of pressure per unit length.

- The electrical gradient creates a movement of ions of one charge to an area of ions of the opposite charge. The result of this current is the transmission of nerve impulses and the contraction of muscle tissue. The ionic particles of the nervous impulse can be visualized in the following simplified process.

- In cellular biology, an electrochemical gradient refers to the electrical and chemical properties across a membrane. These are often due to ion gradients, particularly proton gradients, and can represent a type of potential energy available for work in a cell.n electrochemical gradient has two components. First, the electrical component is caused by a charge difference across the lipid membrane. Second, a chemical component is caused by a differential concentration of ions across the membrane.

Passive Transport Simple diffusion does not require energy and occurs along the concentration gradient. The concentration gradient is the process of particles moving, or diffusing, from an area of higher concentration to an area of lower concentration.
