Kinematics and dynamics are two branches of mechanics that deal with the motion of a particle that plays an important role in robotics and mechanical engineering field.
What is kinematics?
A study that describes the motion of bodies and the system of bodies without taking into consideration of the cause of motion.
What is the dynamics?
A study of the motion of a particle along with their cause like force and torque.
Now let us have a deep insight into the comparison between them and check some difference between kinematics and dynamics.
Key difference :
Kinematics will give you the values of change whereas dynamics provide the reasoning behind it.

Kinematics :
- Kinematics originates from the Greek word kinesis, meaning motion.
- Galileo worked on with his numerous experiments measuring displacement, velocity and acceleration of balls rolling down inclined planes.
- More concern with the movement in general.
- A description of how objects move.
- kinematics describes movement, acceleration, speed, of objects.
- Kinematics is based on the nature of force, nature of the body.
- Kinematics is the geometry of motion.
- Motion is teated geometrically without reference to things like cause and effects.
Dynamics :
- Dynamics from the Greek word dunamis which means power.
- Newton worked on when he formulated his three laws.
- Concern about measuring the causes and quantity of it and how it contributes and relates to the movement.
- It deals with force and why objects move as they do.
- Dynamics describes forces applied to the objects.
- Dynamics is based on the concept of force.
- Dynamics is geometry + physics of motion.
- Motion is treated in terms of trajectories and time so force and motion come in.
