Gradients physics
WebPotential gradient. In physics, chemistry and biology, a potential gradient is the local rate of change of the potential with respect to displacement, i.e. spatial derivative, or gradient. This quantity frequently occurs in equations of physical processes because it leads to … WebFeb 8, 2024 · A linear surface tension gradient influences the force balance along the gradient direction, which results in an in-plane net force in the direction of the gradient [in the x-direction of Fig. 1(b)]. When a certain gradient strength is achieved, the force should be sufficient to overcome static frictional effects.
