Undergrad Can elevons and rudders effectively steer spacecraft in the vacuum of space?
I was afraid of that. But, thank you, that was exactly the information I was looking for. Here's a follow-up question. So for everything besides forward thrust which is provided by the main engines and the maneuvering engines they use the forward control thrusters and aft control thrusters in...- bluej774

Does Black Light Really Exist?
There's no black light in reality, but I know that computer scene-rendering software has an interesting type of beam of non-light that may fit the bill. Pixar has used it in the past. It has most of the properties of a normal beam of light except instead of adding light, it subtracts it. It... -

Undergrad Can elevons and rudders effectively steer spacecraft in the vacuum of space?
Why is it that elevons and rudders like those seen on NASA's various orbiters succeed in adjusting the pitch, roll, and yaw of crafts in the vacuum of space? I was under the impression that such devices relied upon the resistance of air (or water) to function. Why do they work in a vacuum?- bluej774

Using watts to help determine velocity?
I'm doing a simulation. That's why I need this info. I forgot to mention that the object begins at rest. However, the simulation is not in Earth's gravity. It is in a theoretical space without any major gravitational influence.- bluej774

Using watts to help determine velocity?
Well, then, maybe this is a better question. Can you determine force from watts (joules per second) expended producing said force?- bluej774

Using watts to help determine velocity?
Here's what I know about an abstract object: *mass *position *all external forces acting upon it (gravity ;) *that it is exerting force upon itself *direction of said force *number of joules per second being used in said force (watts) Can I use these to determine the velocity of the...- bluej774
