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.
The acceleration, in the frame you defined, is opposite to the positive direction. Do the same problem in both frames of reference. Object is thrown upward with initial speed V0 (notice that I said speed and not velocity: speed is a scalar and velocity is a vector) Case1. Frame of reference: positive direction UP Then the acceleration is negative and the initial velocity is positive. Equation of motion: d = V0t - (1/2)gt^2 Case 2.
