# Is impulsive tension called jerk? [closed]

Jerk is derivative of acceleration, is impulsive tension also the same. Or there is nothing like impulsive tension

• Would you give a bit more context to the question, for example a case you are considering or what do you mean by "impulsive tension", that will help people attempting to help you – ohneVal Sep 13 '19 at 7:50
• you corrected the title, but not the question. Also explain what do you mean – lurscher Sep 13 '19 at 9:49

For example, a particle whose position at time $$t$$ seconds is $$x(t)=t^3$$ metres has a velocity $$\displaystyle v(t) = \frac{dx}{dt}=3t^2$$ metres per second, an acceleration $$\displaystyle a(t) = \frac{dv}{dt}=6t$$ metres per second$$^2$$, and a constant "jerk" $$\displaystyle j = \frac{da}{dt}=6$$ metres per second$$^3$$.
• I find that the practice of calling $da/dt$ by the name "jerk" is not nearly as fully established as the vast majority of other terms in physics. Therefore I would recommend that a student learn that it is used, but aim to avoid it themselves unless they really need a word for rate of change of acceleration. – Andrew Steane Sep 13 '19 at 11:26
