Across
  1. 1. the total horizontal and vertical displacements of a projectile over a distance
  2. 6. a part of a two-dimensional vector in the given direction
  3. 11. the resultant vector is the vector sum of two or more vectors
  4. 12. the study of motion in two directions, including projectile motion and
  5. 14. the highest vertical position along a projectile's trajectory
  6. 15. relating to y-axis and aligns from top to bottom
  7. 17. an object that is acted upon by forces at a constant velocity horizontally and moves vertically through gravity
  8. 18. The acceleration acting on the object is caused by gravity and moves only in a vertical direction
  9. 20. an object thrown or launched into the air, moving under the influence of gravity alone
  10. 21. relating to x-axis and at a right angle to the vertical
Down
  1. 2. the angle of a project's initial velocity that allows it to move in a horizontal direction
  2. 3. the movement of an object in a vertical direction against the direction of gravity
  3. 4. the distance moved by an object horizontally as a result of initial horizontal speed and total time
  4. 5. the shape of a projectile that results from the horizontal component of the velocity while gravity accelerates the vertical component of velocity at -9.81 m/s^2
  5. 7. the movement of a projectile across a horizontal plane due to some sort of force
  6. 8. The velocity stays constant throughout the projectile and stays independent of the vertical motion
  7. 9. the distance moved by an object in a vertical direction as a result of initial vertical velocity and total time
  8. 10. a type of projectile problem that determines how far someone can move and one in which the launch angle isn't always 0
  9. 13. when air-resistance is negligible, projectiles follow projectile trajectories
  10. 16. the total horizontal displacement travelled by a vertically launched projectile
  11. 19. motion
