Procedure: a Place the rubber ball on the concrete floor Observe it the ball wall move by tselt as shown in Figure 1 Figue 1 Figure 2 Figure 3 Concen FO 6. Hold the rubber ball at certain height as shown in Figure 2 c. Release the ball and let is fall as shown in Figure 3 Observe how the rubberball behaved after hitting the concrete Hoor: Questions 13. Did the ball move alone when it was placed on the floor? Why? 14. How did the ball behavea upon hitting the floor after it was released from acertain height? Explan why it behaved that way 15. Are there forces involved in the interaction between the rubber ball and the concrete ficor? t your answer s ves, draw all the forces by using a tows that act on objects (ball & ground) Note: The length of arrow indicates the magnitude (amount) of the force, and the arrowhead is its directon 16. Based on your answer in No 3. idenify the action and reaction force 17. Compare the action and reacton force in terms of their magnitude (amount and direction
