KILCHER HOMESTEAD LIVING MUSEUM. 1  In the early 1940âs Yule Kilcher and his bride Ruth came to Alaska from Switzerland to start a new life in Homer, on the shores of Kachemak Bay. 2  Our family lived the subsistence lifestyle, gathering wild greens, hunting moose and catching salmon for food and growing a large garden.
If the acceleration is negative and the velocity is also negative, the speed of the object increases.Deceleration: It means a reduction in speed or a slowing down. Some confusion is there between deceleration and negative acceleration. Negative acceleration can increase the speed of an object.
But, I thought that shouldn't really matter for the sign of velocity, but for whether it is increasing or decreasing, which the question doesn't care about. I know velocity = displacement/time, and since time is always positive, the sign of velocity should be dependent on displacement. So I put the same signs from displacement into velocity. PS, I don't have any background in physics, this is my summer assignment to which they gave no background and no textbook -.-. The fact that all the signs ended up the same still makes me worried that I am doing/did something wrong.
