What is the Definition of Degree of Freedom?

Click For Summary
SUMMARY

The degree of freedom (DoF) is defined as the number of independent movements a system can perform. In a three-dimensional space, there are six degrees of freedom: linear movements along the X, Y, and Z axes, and rotational movements about those same axes. A body is said to have six degrees of freedom when it is unconstrained, allowing for full motion in all directions. Understanding DoF is crucial for applications in robotics, mechanical engineering, and physics.

Hi everyone, I am a newbie here. Can you tell me what would the best definition of DEGREE OF REEDOM be?
 
Engineering news on Phys.org
It depends on the type of system, but essentially you can think of it as a way something can move. If you think of a mechanical movement, there are 6 basic components that something can move in 3D space. It can move linearly in the X, Y and Z directions. It can also rotate about the same three axes. Gneral motion is a combination of those 6 movements. It is said that the body has 6 degrees of freedom if it is not constrained in any way.
