Terminal Velocity Calculator

How to use the Terminal Velocity Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

terminalVelocity = (2×mass×gravity/(fluidDensity×area×dragCoefficient))^0.5

Frequently asked questions

What is terminal velocity?

Terminal velocity is the maximum velocity an object reaches when falling through a fluid, such as air. At this point, the gravitational force pulling the object downwards is balanced by the drag force acting upwards, resulting in no further acceleration.

How does the Terminal Velocity Calculator work?

The Terminal Velocity Calculator estimates the falling speed of an object based on various factors such as mass, shape, and drag coefficient. Users can input these variables to receive an accurate calculation of the terminal velocity using the formula: v_t = √((2 * m * g) / (ρ * C_d * A)).

What factors affect terminal velocity?

Several factors influence terminal velocity, including the object’s mass, shape, and drag coefficient, as well as the density of the fluid (like air). For example, a skydiver in a spread-eagle position will fall slower than in a head-down position due to the difference in drag area.

Is terminal velocity the same for all objects?

No, terminal velocity varies for different objects. Heavier objects or those with a smaller surface area typically have a higher terminal velocity compared to lighter or wider objects because of the differences in weight-to-drag ratio.

Can you calculate terminal velocity for a human body?

Yes, the Terminal Velocity Calculator can be used to estimate the terminal velocity of a human body. Generally, a skydiver in a free fall position reaches a terminal velocity of about 53 m/s (around 120 mph), while a spread-eagle position may result in a lower velocity of around 45 m/s (about 100 mph).

How can terminal velocity be useful in real-world applications?

Terminal velocity calculations are important in various fields, including aerospace engineering, skydiving, and sports science. Understanding terminal velocity helps in designing parachutes, predicting the behavior of falling objects, and ensuring safety measures are in place for activities involving high falls.
