Answer 2

We know that some vehicles move faster than others. Even the same vehicle may move faster or slower at different times. Make a list of ten objects moving along a straight path. Group the motion of these objects as slow and fast. How did you decide which object is moving slow and which one is moving fast.

If vehicles are moving on a road in the same direction, we can easily tell which one of them is moving faster
