Kinematics: A Complete Picture of Motion Without Causes

Click For Summary
SUMMARY

Kinematics is defined as the study of motion without reference to its causes, encompassing 1-D, 2-D, and 3-D position and motion. Key concepts include velocity as the vector rate of change of position, acceleration as the vector rate of change of velocity, and higher-order derivatives such as jerk and snap. The discussion highlights kinematic constraints, including holonomic and non-holonomic systems, and addresses the motion of inertial and non-inertial reference frames. Additionally, it raises questions about incorporating relativistic and quantum motion into a comprehensive framework of kinematics.

PREREQUISITES
  • Understanding of vector calculus
  • Familiarity with classical mechanics principles
  • Knowledge of reference frames in physics
  • Basic concepts of Special Relativity and Quantum Mechanics
NEXT STEPS
  • Study the principles of Special Relativity
  • Explore Quantum Mechanics fundamentals
  • Research kinematic constraints in depth, focusing on holonomic vs. non-holonomic systems
  • Examine the differences in motion at classical, relativistic, and quantum scales
USEFUL FOR

Students of physics, educators in mechanics, and researchers interested in advanced kinematics and the relationship between motion across different scales.

So, if kinematics is the study of motion without reference to its causes (which is how it seems to be defined in many places), then here is my attempt to come up with a complete picture of motion without reference to its causes. This is just a summary to help me organize my thoughts (it is NOT meant to be a summary only of a first-year course on mechanics; it is meant to summarize everything in the study of motion without reference to its causes like forces).

Here's my "big picture":

1-, 2-, and 3-D position
1-, 2-, and 3-D motion

velocity as vector rate of change of position
acceleration as vector rate of change of velocity
jerk, snap, etc.

kinematic constraints
-holonomic
-non-holonomic

change of orientation of a body (here I don't know how this is generally described)
-rotation of body about a fixed axis

relative velocity and acceleration

point trajectories in a moving body (with velocity and/or acceleration)

motion of inertial reference frames
-rotation
-translation

accelerating reference frames (non-inertial reference frame)My first question is: Am I missing anything?

And my second question is: What is the best way to include here how motion at the relativistic scale and motion at the quantum scale are different from that of motion at the classical scale? In general, is there a way to give an outline that applies to motion at all scales?

Learn Special Relativity; learn a bit of Quantum Mechanics.
 
yaa as we are advancing in physics we are coming to know about 4th d also as published in paper of Albert einstein
