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.
In physics, the use of positive and negative always has a physical meaning. It is more than a mere mathematical symbol. As used here to describe the velocity and the acceleration of a moving object, positive and negative describe a direction. Both velocity and acceleration are vector quantities and a full description of the quantity demands the use of a directional adjective. North, south, east, west, right, left, up and down are all directional adjectives. Physics often borrows from mathematics and uses the + and - symbols as directional adjectives.
