Which branch of physics deals with the effects of force on an object and the movement caused by that force?

The branch of physics that focuses on the effects of force on an object and the movement that results from that force is mechanics. Mechanics is the study of motion and the forces that cause or change that motion. This includes analyzing how different forces interact with objects, how objects move in response to those forces, and the resulting kinematic equations that describe that motion.

Kinematics, while related to mechanics, specifically deals with the motion of objects without considering the forces that cause that motion. Thermodynamics is concerned with heat and temperature and how they relate to energy and work, while electromagnetism focuses on electrical and magnetic fields and their interactions with charged particles. Thus, mechanics encompasses the principles that describe how forces influence the movement of objects, making it the appropriate answer for this question.
