Thanks for the reply I need more explanation on this part For example, I would attached only a thrust fan, position is (x=7.5 ,y=2 in), at the back of the rectangular styrofoam board. Let's assume the fan is a rectangular plane as well. I wanted to get the moment of inertia. So, how will I...

I am doing a mini hovercraft project. Regarding my design, I plan to place the fan (LIFT) in the middle of a rectangular styrofoam board (15 inches by 8inches). The position of my fan would be (x=7.5, y=4in); this would also be my center of gravity. My origin (coordinate) is at the corner of...

Newton's first law says that when an object is at rest or moving in constant velocity, it will stay that way unless external force is applied. So, net force is zero. What I don't get is on an object moving in constant velocity. How is the object begin moving? Is netforce applied initially...
