* Acceleration itself is the change in velocity over time. The standard equation for acceleration is:
a = (v_f - v_i) / t
Where:
* a = acceleration
* v_f = final velocity
* v_i = initial velocity
* t = time
* Change in acceleration is called "jerk". It's the rate at which acceleration changes over time. The equation for jerk is:
j = (a_f - a_i) / t
Where:
* j = jerk
* a_f = final acceleration
* a_i = initial acceleration
* t = time
So, to find the change in acceleration, you essentially calculate the jerk.
Important Note: While jerk is a defined physical quantity, it's not as commonly used as acceleration. It's more relevant in situations where the rate of change of acceleration is significant, such as in high-speed maneuvers or certain types of motion analysis.
