ELI5 Why when you pull a material suddenly it snaps where as if you applied the same force gradually it stretches.

Most basically put, it all depends on what is called strain rate. All materials have defects within the structure, as you move a material the defect moves as well. When the defect can no longer move, the material breaks. Slow movement of the material allows the defect to move within the structure, quick movement restricts the movement of the defect and causes failure.
