- 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 x0 – initial position along x Vox – initial velocity along the x-axis y- final position along y voy – initial velocity along the y-axis t – time g – acceleration due to gravity (9.81 m/s2)
- 29. X = x0+V0xt Y = y0+V0yt-1/2gt2 Equation of Motion
- 30. x 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)
- 32. Take note! The height and range of an object reaches is dependent upon 1.How fast it leaves its initial position(initial velocity) 2.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
- 36. Where: V0x- initial velocity along the x- axis V0y- initial velocity along the y- axis t- time θ- angle between the initial velocity and the x-axis
- 37. X= (V0cosθ)t y= (V0sinθ)t –1/2gt2
- 38. x- final position along x-axis y-final position along y-axis V0- initial velocity Vy- final velocity along y-axis Vx- final velocity along x-axis t- time g- acceleration due to gravity (9.81 m/s2)
- 39. Vx= V0cosθ Vy= V0sinθ –gt

Editor's Notes
- #6: Did you know the Three Laws of Motion? We have Law of Inertia, Acceleration and Equal Reaction. What does Second Law mean?
- #14: Arrange the following words in order to get the definition of the decoded word earlier.
- #20: Please be guided with the following rubrics
- #21: Please be guided with the following rubrics
- #26: Constant – occurring continuously over a period of time
- #33: From the report of group 2 it shows the vehicle speed up . Every minute there is 1 km/h increase on the speed of the vehicle. As you can see the increase in every minute is constant . Therefore we can say that the vehicle has a uniform acceleration. Again, what is uam?
- #34: The X and Y components of the initial velocity with respect to the angle launch given by the equation
- #35: From the report of group 3 and 4 it shows how gravity affect the direction of the motion or force. So, everything that we throw upward will eventually go down because of the gravity. And also the reason why we are not being thrown outside the space
- #45: a
- #46: NOT UAM
