What are the differences between Relative intensity and Absolute intensity?

If anyone is familiar with ‘tony’, then don’t reply to this post.

I think relative intensity would be if you are lifting with a weight that is say your 5RM and you perform 5 reps, you have performed 100% relative intensity and absolute intensity would be using percentages or using ur 1 rm would be 100% absolute intensity. Im not sure though, David W? Coach Thib?
