SUMMARY

The discussion focuses on the relationship between acceleration, jerk, and their graphical representations over time. Jerk, defined as the time derivative of acceleration (da/dt), is characterized by a horizontal line when constant. The graph of velocity over time (dv/dt) exhibits a slope equal to the jerk value, while the position over time graph (dr/dt) resembles a quadratic function, and the position versus time graph (r vs t) resembles a cubic function. These relationships are crucial for understanding motion dynamics in physics.

PREREQUISITES
  • Understanding of basic calculus concepts, specifically derivatives.
  • Familiarity with kinematic equations and motion graphs.
  • Knowledge of the definitions and implications of acceleration and jerk.
  • Basic graphing skills to interpret and create position, velocity, and acceleration graphs.
NEXT STEPS
  • Study the mathematical definitions and implications of jerk in motion analysis.
  • Learn about the graphical representation of kinematic equations in physics.
  • Explore the relationship between acceleration, velocity, and position through calculus.
  • Investigate real-world applications of jerk in engineering and physics simulations.
USEFUL FOR

I understand that
a/t is called "jerk", or change in acceleration.

What would this graph look like as a qualitative position/time graph? (Assuming constant jerk)

And to take it further, what would a jerk/time graph look as a position/time graph?

You mean "da/dt" the time derivative of acceleration.

A horizontal line.
 
if (da/dt) is not zero , it would be a horizontal line 'y=a' where 'a' is the value of jerk.
(dv/dt) would be a line with a slope equal to the value of the jerk.
(dr/dt) would similar to x^2 graph.
(r vs t) would be similar to x^3 graph.
