kinemática

Kinematics is a branch of classical mechanics that describes the motion of points, bodies, and systems of bodies without considering the causes of that motion. It is the study of displacement, velocity, and acceleration. Kinematics is the first step in analyzing motion, as it provides the mathematical language to describe how objects move.

The fundamental concepts in kinematics include position, displacement, velocity, and acceleration. Position refers to the location of an object in space. Displacement is the change in position of an object. Velocity is the rate of change of displacement, indicating both the speed and direction of motion. Acceleration is the rate of change of velocity, signifying how the speed or direction of motion is changing.

Kinematics can be divided into two main categories: one-dimensional kinematics, which deals with motion along a straight line, and multi-dimensional kinematics, which describes motion in two or three dimensions. For one-dimensional motion, equations of motion are often used to relate displacement, initial velocity, final velocity, acceleration, and time. These equations are derived from the definitions of velocity and acceleration.

In multi-dimensional kinematics, vectors are used to represent quantities like position, velocity, and acceleration, allowing for the description of motion in a plane or in space. Analyzing projectile motion and uniform circular motion are common examples of multi-dimensional kinematic problems. Kinematics serves as a foundational subject for understanding more complex areas of physics, such as dynamics, which considers the forces that cause motion.
