Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions).
What is kinematics in simple words?
Kinematics is a subfield of physics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move.
How do you explain kinematics?
Kinematics is the branch of classical mechanics that describes the motion of points, objects and systems of groups of objects, without reference to the causes of motion (i.e., forces ). The study of kinematics is often referred to as the “geometry of motion.”
What is kinematics give three examples?
The examples for kinematics are given below: i) Moving train and bus. ii) Motion of a mass on inclined plane. iii) Running water in the river. iv) Falling water from a mountain peak.
What are the 4 kinematic equations?
There are four kinematic equations when the initial starting position is the origin, and the acceleration is constant:
- v=v0+at. v = v 0 + at.
- d=12(v0+v)t d = 1 2 ( v 0 + v ) t or alternatively vaverage=dt. v average = d t.
- d=v0t+(at22)
- v2=v20+2ad.
Why do we use kinematics?
Kinematics aims to provide a description of the spatial position of bodies or systems of material particles, the rate at which the particles are moving (velocity), and the rate at which their velocity is changing (acceleration).
What are the types of kinematics?
There are three basic concepts in kinematics - speed, velocity and acceleration.
How does kinematics apply to everyday life?
For example, in machine components it is common to use kinematics analysis to determine the (unknown) speed of an object, that is connected to another object moving at a known speed. For example, one may wish to determine the linear velocity of a piston connected to a flywheel that is turning at a known speed.
What is difference between kinematics and kinetics?
Kinetics is focused on understanding the cause of different types of motions of an object such as rotational motion in which the object experiences force or torque. Kinematics explains the terms such as acceleration, velocity, and position of objects.
Who invented kinematics?
Discourses such as these spread throughout Europe, shaping the work of Galileo Galilei and others, and helped in laying the foundation of kinematics. Galileo deduced the equation s = 12gt2 in his work geometrically, using the Merton rule, now known as a special case of one of the equations of kinematics.
What are the two types of kinematic analysis?
In general, kinematic analysis of human movement can be categorized into two main areas: 1) Gross movement of the limb segments interconnected by joints, where the relative three-dimensional joint rotation is described by adopting the Eulerian angle system.
How do you master kinematics?

What is kinematics of machine?
2. KINEMATICS • It is that branch of theory of machine which deals with relative motion between the various parts of machines. • Kinematics describes the motion of points , bodies without consideration of the causes of motion.
