Therefore

Answer:
the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
and/or
Kinematics is the study of motion of a system of bodies without directly considering the forces or potential fields affecting the motion. In other words, kinematics examines how the momentum and energy are shared among interacting bodies.
Answer:
