Question

What is terminal velocity?

Answer 1

Terminal velocity

1. The terminal velocity of an object falling through a liquid or gas is its maximum achievable velocity.
2. This occurs when the fluid's resistance increases as the magnitude of the velocity increases.
3. As soon as the resistance equals the driving force, the object reaches terminal velocity.
4. In expression it is written as: $V_t=\sqrt{\frac{2mg}{\rho A{C}_d}}$ Here, $V_t=terminalvelocity,m=mass,g=accelerationduetogravity,\rho =densityofthefluidthroughtheobjectisfalling$ and $A=projectedareaoftheobject,C_d=dragcoefficient.$
