Of course there are multiple formulas to help you calculate everything you ever wanted, including the terminal velocity of a falling object. However, Free-Fall Calculator is a nice app that does the math in an instant, saving you a lot of time.
The program has a simple interface and a clean layout, so figuring out how to work with it should be easy.
As mentioned, the program can calculate the terminal velocity of a falling object, as well as some vacuum formulas.
For instance, you have to fill in the exact mass, cross sectional area and the drag coefficient, as well as the air density. When you want to calculate the later, the program requires to input the altitude. Once all these details are filled in, the program can tell the exact value.
When trying to make vacuum calculations, you need to choose the type of formula you want to use. You may choose between time, velocity and distance.
The program enables you to solve problems either in metric or English units, so it should be easy to handle by users from all over the world.
All in all, Free-Fall Calculator is a nice tool that can be useful to have around, especially if you often deal with this type of math. Inexperienced users should find the program easy to handle, thanks to the intuitive layout.
