Thank you for the opportunity to help you with your question!

Dynamic:  the force generated causes movement at the joint

Static: the muscle generates force while the joint angle remains the same. 

Concentric: force is generated as the muscle shortens and the joint angle decreases (positive phase)

Eccentric: force is generated as the muscle lengthens and the joint angle increases (negative phase)

Please let me know if you need any clarification. I'm always happy to answer your questions.
