# Definition of kinematics

Physics> Define Kinematics

Kinematics – the study of the movement of points, objects and groups of objects without considering the reasons for the movement.

## Learning challenge

Definition of the concept of “kinematics”.

## Key points

• To describe motion, kinematics examines the paths of points, lines, and other geometric objects.
• The study of kinematics can be reduced to mathematical expression.
• Kinematic equations are used to calculate various aspects of motion, such as speed, displacement, acceleration, and time.

## Term

Kinematics is a branch of mechanics that studies the movement of objects, but ignores the forces associated with it.

Kinematics is a section of classical mechanics that describes the movement of points, objects and entire groups, but does not take into account the forces that affect the entire process. Kinematics are often referred to as “motion geometry”.

Look around and you will notice that objects around you are in mechanical motion. Moreover, while you sleep, your blood continues to circulate through your veins. Even inanimate objects remain active as atoms and molecules move. The ability to understand movement not only answers interesting questions, but also helps to understand the rest of the concepts in physics. For example, you cannot study strength without understanding the acceleration process. To describe motion in kinematics, one should make friends with the trajectories of points, lines and other geometric objects, as well as their differential properties (acceleration and speed). That is, it is important to understand the basics of kinematics and its application in physics. Kinematics is used in astrophysics to describe the movement of celestial bodies and systems. She is actively involved in mechanical engineering, robotics and biomechanics.

Formally speaking, the very study of physics begins with the basics of kinematics. This word has Greek roots (“kinesis”), meaning movement. Kinematic analysis – the calculation of kinematic quantities that are used to describe motion. Kinematics can be simplified to mathematical expression and used to calculate various aspects of motion such as speed, time, acceleration, trajectory, and displacement.
