Terminal Velocity

Terminal velocity is the maximum velocity of a body moving through a viscous fluid.It is attained when force of resistance of the medium is equal and opposite to the force of gravity.

As the velocity is increasing the retarding force will also increase and a stage will come when the force of gravity becomes equal to resistance force.

After that point velocity won’t increase and this velocity is known as terminal velocity.It is denoted by ‘vt’.Wheret=terminal.

Mathematically:-Terminal velocity is attained when Force of resistance = force due to gravitational attraction.6πηrv =mg6πηrv = densityxVg (Because density=m/V), density=ρ – σ where ρ and σ are the densities of the sphere and the
viscous medium resp.6πηrv = (ρ – σ)x4/3πr3g where Volume of the sphere(V) =4/3πr3By simplifying=(ρ – σ)gx4/3r2x1/(6η)vt =2r2(ρ – σ)g/9 η .This is the terminal velocity. Where(v=vt)

If a particle is moving inside a liquid then after some time its velocity will become constant as net force will become zero is called terminal velocity
