PHYIC CALCULATOR
Terminal Velocity Calculator
A precise tool.
What is the Terminal Velocity Calculator & How does it work?
Terminal velocity is the constant speed that a falling object eventually reaches when the force of gravity is balanced by the drag force.
v = sqrt{frac{2m g}{rho A C_d}}
v = terminal velocity, m = mass of the object, g = acceleration due to gravity, rho = air density, A = cross-sectional area, C_d = drag coefficient
This formula assumes that the object is falling in a vacuum and that the fluid (air) is homogeneous.

Frequently Asked Questions
What is terminal velocity?
Terminal velocity is the constant speed reached by a falling object when the force of gravity is balanced by air resistance.
How do I calculate terminal velocity?
Use the formula v = sqrt(2mg / (ΟACd)), where m is mass, g is gravity, Ο is air density, A is cross-sectional area, and Cd is drag coefficient.
What factors affect terminal velocity?
Terminal velocity depends on the object’s mass, gravity, air density, cross-sectional area, and drag coefficient.
Can I use this calculator for liquids other than air?
This formula assumes air as the fluid. For other fluids, you need to adjust the air density (Ο) accordingly.
What is the difference between terminal velocity and free fall speed?
Terminal velocity is reached when forces balance, resulting in constant speed. Free fall speed increases until it equals terminal velocity.
How does shape affect terminal velocity?
The cross-sectional area (A) and drag coefficient (Cd) are influenced by the object’s shape, affecting its terminal velocity.
Is terminal velocity always the same for objects of different masses?
No, terminal velocity varies with mass; heavier objects generally reach higher terminal velocities under similar conditions.
