xD xD ​

Kinematics is the study of motion, without any reference to the forces that cause the motion. It basically means studying how things are moving, not why they're moving. It includes concepts such as distance or displacement, speed or velocity, and acceleration, and it looks at how those values vary over time.

Kinematics is the branch of mechanics concerned with the motion of objects without the reference to the forces which cause the motion.
