What is the dimension of the jerk?

Question

The rate at which the acceleration of an object changes with time is called the jerk?

Answer 1

m/sec^3

Answer 2

The derivative of acceleration, the rate of change of acceleration with respect to time, is a quantity known as the "jerk". Jerk is measured in m/sec^3.

There is no end to this! You can always calculate something as rate of change of jerk, and .then its rate of change... ad infinitum. But in the practical physical world interpreting something—beyond—jerk is much too difficult.

Acceleration is an initial value plus the time integral of "jerk"—just like velocity is the initial value plus the time integral of acceleration. Much the same holds from velocity to position. If you want to work it out in direction, do the calculus with vectors.

Moment of inertia is relevant when considering a body's rotation. If the acceleration is independent of this then, it is irrelevant. A rocket's thrust direction is dependent upon the way it is pointing. The force on a charge in a field depends on it's position in the field.
___________________

Anytime we encounter a "jerk", that is to say, a fast pulse of any kind in any media, we encounter "excess" energy. Electrically, we find this in situations such as Tesla's "magnifying transmitter" designs, where explosive electrical discharges dissociate electrons into their sub-quantum components, resulting in multitudinous kinds of "anomalous" events.

Answer 3

Since it is the time derivative of acceleration is should be m/sec/sec/sec or m/sec^3.

Answer 4

Yeah (m/s^3), or more commonly, (m/s^2)/s from what I see in some textbooks.

I think it is commonly used by engineers that deal with engines.
