Definition Of Force Gradient
A concentration gradient takes place when ions or particles labeled as solutes begins to move from a higher concentration of particles in a solution to lower the concentration particles.
Definition of force gradient. A difference in pressure across a surface then implies a difference in force which can result in an acceleration according to newton s second law of motion if there is no additional force to balance it. Making use of the hydrostatic equation 3 17 and the definitions of geopotential 3 20 and geopotential height 3 22 the horizontal pressure gradient force can be expressed in the alternative forms. In general a pressure is a force per unit area across a surface. The pressure gradient force is the force produced when air with different pressures are placed next to each other.
Pressure differences occur in the atmosphere due to differences in the density of air. A membrane separates both regions from each other. Concentration gradient definition biology. The pressure gradient force is directed down the horizontal pressure gradient p from higher toward lower pressure.
An osmotic gradient is a pressure that forces solvent particles to move from a higher. For instance in the case of atmospheric pressure the pressure gradient can be balanced by the gravitational force while maintaining the hydrostatic equilibrium. The pressure gradient force is the force that results when there is a difference in pressure across a surface. The pressure gradient force flows from higher pressure to lower pressure and the process continues until the pressure is equalized.
And absent external forces acting on the particle.
