To better understand the setup, we should look at it from the side view (above).

As the ball (ball A) on the bumpy track reach the grey part, its height its lower than that of the ball (ball B) along the straight track.

At the lower height more GPE of ball A would have been converted to KE (compared to ball B). So the speed of ball A would be faster then ball B.

1. clarifying and understanding learning intentions and criteria for success

2. engineering effective classroom discussions, questions and tasks that elicit evidence of learning

3. providing feedback that moves learners forward

4. activating students as instructional resources for each other, and

5. activating students as owners of their own learning
