I am completely lost on how to convert velocity time graphs into acceleration time graphs. so far all i no is to break the velocity graph into sections/intervals and find the area. the answer i get for the area is the scale on my y axis of my acceleration graph. but what i do not no is what kind of line would it be on the acceleration graph (like would my line be straight and positive or straight and negative or would it be just a horizontal line) and how to determine that? Also how do i convert graphs that go from a positive scale to a negative scale in one graph? any help would greatly be appreciated!! Thank you!
