What is degree of freedom??.. |
|
Answer» \tDegrees of Freedom can be defined as independent displacements or rotations that specify the orientation of a body or system.\tA molecule free to move in space needs three coordinates to specify its location.\tIf it is constrained to move in a plane it needs to.\tIf constrained to move along a line, it needs just one coordinate to locate it.\tFor example:-Consider a room and if we tie a thick rope from one wall to another.Take a ball which is moving straight on the rope.The ball has only 1 degree of freedom. It can move only in one particular dimension. Consider if the ball is on the floor which is two-dimensional, then the ball can move along 2 directions.The ball has 2 degree of freedoms. Consider if we throw the ball in space which is 3 dimensional. Then the ball can move in 3 dimensions.Therefore degree of freedom tells us in how many ways a body can move or rotate or vibrate.\t\t Just remember the values Number of ways in which molecule can store energy |
