Define terminal velocity find experastion for it? Class 11
Answers
Answer
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.

Answer:
The fastest speed at which an object can descend through a fluid is known as terminal velocity.
Explanation:
What is Terminal Velocity?
- An object falling through a fluid at its greatest speed is said to have reached its terminal velocity.
- When the combined drag and buoyancy forces are equal to the force of gravity pulling the object downward, it is observed.
- Since there is no net force exerted on the object, there is no acceleration of the object.
- According to fluid mechanics, an item must maintain a constant speed while travelling against the force of the fluid it is moving through in order to reach its terminal velocity.
- The following equation represents terminal velocity mathematically:
vt = √2mg/ ACd
- Where,
m is the mass of the falling object, g is the acceleration caused by gravity, Cd is the drag coefficient, density of the fluid through which the object is falling, and A is the area projected by the object.
