What is Kinematics?
Kinematics is a discipline of physics and mechanics, responsible for studying and describing the movement of objects in terms of trajectory and time variables. The term kinematics originates from the Greek word κινέιν or kinéin, which means ‘to move or displace’.
This discipline is not concerned with determining the causes that generate movement, but is basically aimed at describing displacement to identify its duration.
Principles of kinematics
Therefore, the essential elements that the kinematics analyzes are the mobile, the space and the time. From them, the kinematics considers the study of the magnitudes, which correspond to: position, speed and acceleration.
- The position:refers to the place where the mobile is located, which is represented with a position vector.
- Speed:determined by evaluating the distance traveled in time.
- Acceleration:corresponds to the variation of said speed during its displacement in time.
Types of kinematics
The kinematics has allowed the classification and analysis of different types of movements. Among them we can mention:
- Uniform rectilinear motion.
- Accelerated rectilinear motion.
- Uniformly varied rectilinear motion.
- Uniform circular motion.
- Accelerated circular motion.
- Curvilinear motion.
