How to relate kinematics of a moving frame and that of a laboratory frame?

AI Thread Summary
To relate the kinematics of a moving frame to a laboratory frame, one can use the Galilean transformation for velocities and rotations when dealing with non-relativistic speeds. If the object's velocities are known in a moving frame, it is essential to clarify the frame's relationship to the object to obtain accurate information. For scenarios involving speeds approaching the speed of light, the Lorentz transformation must be applied to account for relativistic effects. The discussion emphasizes the importance of clearly defining the frame of reference to derive meaningful kinematic relationships. Understanding these transformations is crucial for accurate analysis in physics.

Hi all, if I have the velocities and rotations of an object with respect to a moving frame.
Are there relations that I can obtain the velocities and rotations of the object with respect to a fixed frame?

I think you need to state your question more clearly edoctor.

Usually when you say that you have information about an object in a certain frame it presupposes that this frame is fixed relative to the object so no more velocities and so on need to be added into get the "real" information.. If you don't have the "real" information already, you don't have information about the object in this frame of reference...
 
Use the Galilean transformation. If there are velocities involved close to the speed of light, then you will need to include effects due to Einstein's relativity by using the Lorentz transformation.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
