Question

define Terminal velocity. derive an expression for it
​

Answer 1

Answer:

maximum constant velocity acquired by a body while falling through a viscous medium is called its Terminal Velocity. # It is attained when force of resistance of a medium is equal and opposite to the force of gravity. DERIVATION: Expression for terminal velocity, V = Vt.Nov

Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid. It occurs when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object. Since the net force on the object is zero, the object has zero acceleration.
