Exercise 8A: Vectors and Motion
Each diagram on the right shows the motion of an object. Each dot is one location of the object at one
moment in time. The time interval from one dot to the next is always the same.
1. Suppose the object in diagram 1 is moving from the top left to the bottom right. Figure out what kind
of force is acting on it. Does the force always have the same magnitude. The same direction.
Invent a physical situation that this diagram could represent.
What if you reinterpret the diagram, and reverse the object’s direction of motion.
2. What kind of force is acting in diagram 2.
Invent a physical situation that diagram 2 could represent.
3. What kind of force is acting in diagram 3.
Invent a physical situation.
