2. What will happen to the ball if it will roll on top of the table?

3. What happens when the ball rolls against the surface? What causes the ball to suddenly stop from rolling?

4. Why do you think the ball suddenly stop from rolling/ moving after sometime?

5. How will you compare the movement of the ball on the grassy surface and a ball on a wooden surface?

6. Why these objects slow down or stop as they move along different surfaces?

7. What is FRICTION?

8. Friction is a force that resists/ opposes the motion of one object against another . All objects moving on a specific surface stop at different rates because of an opposing force called FRICTION.
