Final answer:
Dynamics is the study of how forces affect the motion of objects and systems. It is a branch of physics that deals with motion and the forces causing it. Isaac Newton's laws of motion are the foundation of dynamics.
Step-by-step explanation:
Dynamics is the study of how forces affect the motion of objects and systems. It considers the causes of motion and is the branch of physics that deals with motion and the forces causing it. Isaac Newton's laws of motion are the foundation of dynamics and provide universal principles that apply to situations on Earth and in space.
