... Figure (a) shows velocity as downward, so the object is moving down. The length of the vector increases with each step showing that the speed is increasing (like a dropped ball). Thus, the acceleration is directed down. Since F ma the force is in the same direction as the acceleration and must be ...

... Aristotle thought that objects preferred to be at rest…even if they were previously moving. Newton’s first law tells us that this isn’t true—objects actually like to keep doing exactly what it is they’ve been doing (be it standing still or moving), unless some outside force causes them to do somethi ...
