Undergrad What is the difference between covariance and invariance in special relativity?

Click For Summary
In special relativity, an invariant quantity remains constant across all frames of reference, while covariance refers to how certain quantities transform between different frames. Invariance indicates that the value does not change regardless of the observer's motion, whereas covariance allows for the calculation of values in different frames by applying transformation rules. The discussion highlights the importance of understanding these concepts for grasping the principles of special relativity. Additional resources, such as Wikipedia articles on covariance and Lorentz covariance, provide further clarification. Understanding these distinctions is crucial for studying the effects of motion on physical quantities in relativity.

Can anyone briefly explain the difference between covariance and invariance in terms of special relativity?

My understanding is that an invariant quantity is a value which does not change regardless of frame of reference it is being measured in.

Covariance is a value which when measured in different frames of reference can be deduced by accounting for the transformation properties between the different frames?

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
