  1. Projectile Motion vo Launch a projectile horizontally from the top of a cliff. Draw the subsequent path of the projectile marking the position of the projectile at equal intervals of time.

  2. Projectile Motion How much time has passed between subsequent positions? 1 unit of time

  3. Projectile Motion How much time has passed between subsequent positions? 1 unit of time

  4. Projectile Motion How much time has passed between subsequent positions? 1 unit of time

  5. Projectile Motion Draw a horizontal and vertical line extending away from the the projectile’s initial position. Draw an outline of the projectile at each pair of intersecting lines Draw a pair of horizontal and vertical line from each position.

  6. Projectile Motion Describe the horizontal displacements. How much time passed between subsequent positions? What’s the displacement between subsequent positions? 1 unit of time 1 unit 1 unit 1 unit Horizontal Displacements are EQUAL

  7. Projectile Motion Describe the vertical displacements. 1 unit How much time passed between subsequent positions? What’s the displacement between subsequent positions? 3 units 1 unit of time 5 units x’s = Consecutive ODD #s

  8. Projectile Motion What does each vertical side of a colored region represent? 1 Left Side xDisplacement 3 ConsecutiveODDNumbers 5

  9. Projectile Motion Describe the motion of the projectile at subsequent positions. CONSTANTHorizontalVelocity

  10. Projectile Motion Describe the motion of the projectile at subsequent positions. CHANGINGVerticalVelocity

  11. Projectile Motion vx vx vx vx Draw an arrow representing the horizontal velocity at each position.

  12. Projectile Motion vy vy vy Draw an arrow representing the vertical velocity at each position. vx vy=0 vx vx vx

  13. Projectile Motion Draw an arrow representing the speedat each position. vx vx vy vx vy vx vy

  14. Projectile Motion 90 90 Use your knowledge of right triangles to draw in the speed.

  15. Projectile Motion v v v v Draw an arrow representing the speedat each position. vx vy vx vy vx vy

  16. Projectile Motion 90 Use your knowledge of the Pythagorean theorem calculate the speed. vx vy v v2=vx2+vy2

  17. Projectile Motion ag ag ag ag Draw an arrow representing the acceleration at each position. v=vx vx vy But guess what… v vx vy v vx vy v

  18. Projectile Motion v=vx vx ag vy ag v vx ag vy v vx vy ag v

  19. Kinematics Equations You can still use all these…but just be sure to keep you keep the x and y dimensions separated!

  20. Projectile Motion • You gotta ‘Keep ‘em separated….’ The X-stuff The Y stuff Horizontal Motion Vertical Motion
