Homework 7 Mechanical work We learned that in order to change
... We learned that in order to change kinetic energy of an object we have to change the absolute value of its velocity (the speed). To do that we need acceleration and, hence, force (we know very well that there is no acceleration without force). But it is not enough just to apply force. We also know t ...
