Can I have a good explanation of what exactly is Tension? I appreciate simple answers.
Also, this is my intuition on tensors:
It is a vector that doesn't follow vector laws. Is this true? I would appreciate any
corrections to my current definition.
A tensor is not a physical quantity per se. In some cases, a tensor (rank 0 or 1) may represent a scalar or vector quantity but in a general sense, It is a mathematical tool or expression that Physicists use to express a physical state that has multiple directional properties. For example, stress itself is a scalar. But the state of stress in a bulk material is a tensor. The state of stress is not a physical quantity. It is simply a description of a number of variables that have different directional properties. To express this state mathematically, we use a device called a tensor.
