Group Presentation

23. Group Presentation Who among you know how to get the velocity of specific motion?

24. Horizontal and Vertical Components of Trajectory

25. The horizontal component of projectile motion (with respect to the x-axis) has an acceleration equal to zero (a = 0) x

26. Since the horizontal component of the velocity of projectiles is constant.

27. The vertical component of acceleration is constant which is equal to the acceleration due to gravity of objects on earth (a = -g) y

28. Where: x – final position along x x – initial position along x V ox – initial velocity along the x-axis y - final position along y v oy – initial velocity along the y-axis t – time g – acceleration due to gravity (9.81 m/s2)

29. X = x +V 0x t Y = y +V 0y t-1/2gt 2 Equation of Motion

30. Where: v x - final velocity along the x axis V 0x - initial velocity along the x-axis V y - final velocity along the y-axis V 0y - initial velocity along the the y-axis T - time G - acceleration due to gravity (9.81m/s2)

31. V x =V 0x V y =V 0y -gt Equation of Motion

32. Take note! The height and range of an object reaches is dependent upon How fast it leaves its initial position(initial velocity) The angle at which it leaves from its initial position (angle of launch)

33. Components of 2-dimentional motion in terms of initial velocity and angle of launch

34. V 0x =V cos θ V 0y = Vsin θ

35. Where: V 0x - initial velocity along the x-axis V 0y - initial velocity along the y-axis t - time θ - angle between the initial velocity and the x-axis

36. X= (V cos θ )t y= (V sin θ )t –1/2gt 2

37. Where: x - final position along x-axis y -final position along y-axis V - initial velocity V y - final velocity along y-axis V x - final velocity along x-axis t - time g - acceleration due to gravity (9.81 m/s2)

38. Vx = V cos θ Vy = V sin θ – gt

43. Short Quiz

44. 1.At what axis is horizontal motion usually associated? x-axis y-axis z-axis w-axis

45. 2. Which is TRUE in the following statement? The projectile motion is the combination of horizontal motion with constant axis and vertical motion with constant acceleration. The projectile motion is the combination of x and y axis. The projectile motion is the combination of position and velocity. The projectile motion is the combination of both height and range.

46. 3. What is the right equations to determine the motion in x and y-axis? 𝑥 = 𝑥 + 𝑣 𝑜𝑥 𝑡 and B. x = x 0 + V0xt C. 𝑥 = (𝑣 cos𝜃)𝑡 D. v 0x = v cos θ

47. 4 . What is the equations for the initial velocity? v 0x = v cos θ and v 0y = v sin θ v 0y = v sin θ only v 0x = v cos θ only none of the above

48. 5. At what aspect of your life where projectile motion where observes or occurs? (1 point)
