SUMMARY

The property that two bodies connected together accelerate with the same acceleration when one of them is subjected to an external force is known as "rigid motion" or "Born rigid motion" in the context of relativity. This principle is exemplified by a person inside an accelerating elevator, where both the elevator and the person experience the same acceleration. The condition for this property to hold is that the connecting medium, such as a rope or string, must not stretch, ensuring a fixed distance and orientation between the two objects.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with the concept of acceleration
  • Basic knowledge of rigid body dynamics
  • Introduction to relativity and its terminology
NEXT STEPS
  • Research the principles of Newtonian mechanics and their applications
  • Study the concept of rigid body motion in classical mechanics
  • Explore the implications of Born rigid motion in the theory of relativity
  • Examine examples of acceleration in non-inertial reference frames
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of connected bodies and the principles of motion in both classical and relativistic contexts.

Does the property that two bodies connected together and if one of them is accelerating with some acceleration the second also accelerates with the same acceleration, have a name? Like for example, if there is a person in an elevator and the elevator is accelerating with acceleration ##a##, then the person also accelerates with acceleration ##a##. Is there a name for this property? Or is not a property because it is so logical that it is said so because it makes sense?
 
Physics news on Phys.org
When to masses are connected with a rope or string, the condition is that the rope or string not stretch.

More generally, there needs to be a fixed distance and orientation between the two objects the for their acceleration to be the same.

What about the case for a person inside an accelerating elevator?
 
It is called rigid motion or, in relativity, Born rigid motion.
