What is Stoke’s Law?
Stoke’s Law is an equation that expresses the velocity of small spherical particles in a fluid medium. The law is established by taking into account the forces acting on a certain particle as it falls through a liquid column under the influence of gravity.
Stoke’s Law Definition
Stokes Law state that, “There is a drag force working on the spherical body which is following in a column and the upward drag force on the body ultimately equals the gravitational force then the body drops with a constant velocity.”
The force that retards a sphere passing through a viscous fluid is directly proportional to the sphere’s velocity, radius, and fluid viscosity. Sir George G. Stokes, an English physicist, stated the viscous drag force acts on a body dropping in a liquid, this force is denoted using the letter ‘F’.
Stoke’s Law
Stoke’s Law: Observe a raindrop falling from a height if you look closely you will notice that the speed of all the raindrops is constant and even though it falls from a height under the influence of gravity its velocity seems constant. These questions are answered using Stoke’s law
Stoke’s law was first proposed by the famous English scientist George Gabriel Stokes. This law tells us that the velocity of any object increases gradually when it is dropped in any medium until it reaches a constant velocity then that object proceeds without changing its velocity.
