The term "kinematical," derived from the word "kinematics," refers to the study or description of motion, specifically in terms of position, velocity, and acceleration, without considering the causes of motion. It pertains to the purely geometrical aspects of motion, rather than the forces involved or the impact of energy on an object.
In the context of physics, "kinematical" is often used to describe systems, equations, or theories that focus on the spatial and temporal characteristics of movement. It is concerned with analyzing and calculating the displacement, speed, and acceleration of objects solely based on their positional changes and time intervals. For instance, kinematical analysis can be used to study the motion of objects falling under gravity or to determine the trajectory of projectiles.
The kinematical description of motion does not require knowledge of the underlying dynamics governing the movement. It solely concentrates on the kinematic variables, ignoring factors such as mass, gravitational force, or friction. This approach allows for a simplified analysis of motion, making it easier to model and predict object trajectories.
In summary, "kinematical" refers to the branch of physics that deals with the purely mathematical description of motion, devoid of the influence of external forces. It enables the measurement and calculation of positional changes, velocities, and accelerations, providing insights into the fundamental aspects of movement.
