At any given time, zero velocity for an object is attained by using its rest frame.channeled intuition said:
No such thing. There are lots of threads here on the PF about reference frames (there are no absolute frames of reference). I'll see if we have a FAQ that covers this for you...channeled intuition said:
Sure, but they wouldn't be pointing in the same direction nor would there be anything "universal" about that. I'm not really sure what you are trying to say with your "proposition". It doesn't make a lot of sense but implies something known to be false (the existence of a universal rest frame).channeled intuition said:
Suppose two distant telescopes are pointed at the same quasar. If you take a gyroscope, align it's axis with the quasar at one telescope, and transport the gyroscope to the other telescope, then you will find that it does not align with the quasar.channeled intuition said:
The last time I discussed absolute frames of reference was many years ago with a couple of fellow physics graduate students. We came up with the brilliant idea that the center of mass of the Universe must be at absolute rest. Proof: If it moved, where would it go? Needless to say we were under the influence.berkeman said:
Zero velocity refers to the state of an object where its speed and direction are both zero. This means that the object is not moving at all.
Zero velocity can be attained in several ways, such as by stopping the motion of an object that was previously moving, or by starting from rest and not moving at all.
Zero velocity is important because it is a key concept in understanding motion and the laws of physics. It also plays a crucial role in many real-world applications, such as in transportation and engineering.
Yes, an object can have zero velocity and still be accelerating. This is because acceleration is a change in velocity, so if an object's velocity is zero but changes over time, it is still considered to be accelerating.
Zero velocity is directly related to an object's position. When an object has zero velocity, it is not moving, and therefore its position remains constant. This can be seen in the position-time graph, where a horizontal line represents zero velocity.
