Change in acceleration (jerk) how to calculate please help!!! im a grade 11 student and i got a question that i dont understand, here it is. 32) a) derive an equation for the change in acceleration by using a graph analysis technique on a a-t (acceleration vs time) graph. (note. The name given tothe change in acceleration per unit time is called a jerk) b) write an equation for the area under the graph . what does this represent. so I thought that the equation to calculate acceleration in a = v/delta t but i dont have any clue what the equation is for the change in acceleration, i figure maybe if they were two straight lines you could just do a2 - a1 = change in acceleration, but on a a-t graph how would that work, because it would have to be two straight lines, not a diagonal line... if any one has any ideas that would be great.
