A stone is shown at rest on the ground. A. The vector shows the weight of the stone. Complete the vector diagram showing another vector that results in zero net force on the stone. B. What is the conventional name of the vector you have drawn? Here is a stone at rest suspended by a string. A. Draw force vectors for all the forces that act on the stone. B. Should your vectors have a zero resultant? C. Why, or why not? Here the same stone is being accelerated vertically upward. A. Draw the force vectors to some suitable scale showing the relative forces acting on the stone. B. Which is the longer vector, and why?
