20. Height and Range of a Projectile

21. Projectile motion is the combination of horizontal motion with constant velocity(acceleration=0) and vertical motion with constant acceleration.

22. The height and range of a projectile are dependent upon initial velocity angle of launch

23. The trajectory of a projectile is parabolic.

24. At the maximum height, the vertical component of the velocity is equal to zero ( vy =o)

25. Before the maximum height, the object is ascending or its height is increasing.

26. After the maximum height, the object is descending or its height is decreasing .

27. Elaborate

28. Can you share some experiences in your life that shows projectile motion?

29. 2 .How do you say that it shows projectile motion?

30. 3.What factors do you think affects how far the projectile you used will land?

31. Generalization

32. Short Quiz

33. What factors affects how far a projectile will land? angle of launch initial velocity both angle and initial velocity None of the above

34. 2. What are the components of projectile motion? x and y axis, initial velocity and time x and y axis, maximum height, time, total time, acceleration due to gravity, initial velocity and parabola x and y axis, maximum height total time, and gravity x and y axis, initial velocity, maximum height and gravity

35. 2 . Where does the height and range of a projectile depend on? initial velocity angle of launch both initial velocity and angle of launch none of the above

36. 4. Which of the following statement is TRUE? Before the maximum height, the object is ascending or its height is increasing and vice versa. Increase in velocity implies increase decrease in height and range At the maximum height, the vertical component of the velocity s equal to ten None of the above

37. 5.How the concept of projectile motion can help you in sports? (1pt)

38. Assignment

39. Study the projectile and projectile motion and the height and range of projectile. Be prepared for the summative test.
