According to the dictionary, dynamics is the study of the relationship
between motion and the forces affecting motion. Dynamics is that part
of the field of mechanics that studies objects in motion, as opposed
to statics. It is the combined study of kinetics and kinematics.
Kinematics is the study of motion exclusive of the influences of mass
and force. It includes displacement, velocity, and acceleration
without regard for the forces acting on a body. It is a mechanical
concept, a subdivision of dynamics.

Very loosely, dynamics answers the question "What are the equations of
motion?", while kinematics answers the question "What are the solutions of
the equations of motion?"

Basically, dynamics includes forces while kinematics does not.

Kinematics has to do with the description of motion (position, velocity,
acceleration, etc) while dynamics has to do with the explanation of that
motion in terms of forces and torques.

Not quite. Kinematics answers the question "What is the general form of
objects that are subject to the dynamics?" Thus it only tells you
about conceivable solutions. But kinematics does not know of
equations of motions, and hence can only tell general (kinematical)
features of solutions.
