Terminal Velocity

[cheesetacos234]

I was playing around on Algodoo and i found out that objects don't have terminal velocity, i think it is a very necessary and obvious thing to in the have put in.

[KarateBrot]

why do we need a speed limit for objects? a speed limitation for objects sucks and is unrealistic.

[Conundrumer]

Technically, it is realistic. However, this calls for implementation of aerodynamics in general.
Terminal velocity, ignoring buoyancy, is defined as the following equation:

Where:
Vt = terminal velocity,
m = mass of the falling object,
g = acceleration due to gravity,
Cd = drag coefficient,
ρ = density of the fluid through which the object is falling, and
A = projected area of the object.
The drag coefficient and projected area of the object requires consideration of the shape of the object, something unsupported by Algodoo.

Yeah, the essence is that the terminal velocity is based on a drag force nullifying all other forces acting on an object. On a free-falling object this is usually the aerodynamics of the object which limits its ability to accelerate. In Algodoo, aerodynamics is not yet implemented, however, if I am not mistaken, the air friction would give a terminal velocity on a free-falling object.

Try it yourself, make a box, delete the bottom killer plane, visualize all forces and follow it with the camera. Start the simulation. Then play around with the density of the object to see how it affects the objects ability to accelerate.

I've tested this on a few occasions and there is a terminal velocity.

No there isn't terminal velocity. I dropped a ragdoll from diffrent heights onto a sea-saw where there was another ragdoll and the falling ragdoll never reached terminal velocity.
EDIT: I would post the scene but it seems to have disapeared! Where the heck did it go?

Did you drop it from 10 meters? Explain more clearly.

yes well it doesn't automatically reach that speed, it has to accelerate first. and maybe you didn't save it , try dropping boxes with different weights and air frictions and you will see that it does exist, other wise the object would end up going that fast that it would stop existing

[KarateBrot]

Oh, THIS is terminal velocity... Sorry I didn't know the english word for it so I thought it would be something different.

Yeah there is a terminal velocity. I can calculate it with this little device for a specific object if anyone wants it. Just say "here" if someone is interested.
