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.
Yes...acceleration is the rate of change of velocity with time.....therefore when velocity is zero..definitely acceleration is zero. This is not exactly true; at an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time. An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going upward to going downward, passing through zero for an instant). However the acceleration is downward the entire time.
