Possible teaching ideas:
(1) Click the "Stop Every Hour". Get the students to see what happens every hours
Possible questions to ask:
Where is the object after 1 hr?
Where is the object after 2 hr?
Can you see the pattern?
(2) One of the typical question is to see what is the distance between 2 objects after some time.
Get them to see the relationship between the difference in speed and the distance between 2 objects
(3) Collision or when they meet type of question?
Get the students to articulate what do they observe when the two objects meet?
Possible hints: What is the distance in distance between the two objects?
If the objects are moving in opp direction, what is the distance between Town B and obj1 and Town A and obj2?
If the objects are moving in the same direction, what is the distance between Town B/Town A?
(4) Use the simulation to highlight the difference between the position of the object (i.e., distance with reference to Town A or B) and distance moved.
