  1. Projectiles 1. Launched Horizontally: Stunt Car off Cliff Only affected by gravity. Moving without touching a surface. 3 possible shapes 2. Launched up at an angle: Football Punt 3. In orbit: Satellite in orbit

  2. (Think and share with a partner.) Which of the three shapes do you like best? Why? 1. Launched Horizontally 2. Launched up at an angle 3. In orbit

  3. Which will stay in the air the longest? Why? • Which will stay in the air for the least amount of time? 2. Launched up at an angle 1. Launched Horizontally 3. In orbit

  4. Horizontal and vertical velocities are INDEPENDENT of each other.

  5. Horizontally: travel with constant speed. x = horizontal displacement = horizontal velocity = horizontal acceleration = 0

  6. Vertically: motion is accelerated due to gravity. • Same as for falling objects. y = vertical displacement = vertical velocity = vertical acceleration = g = -9.8

  7. Learning Check • Which velocity of a projectile is constant? • Which velocity of a projectile is accelerated? • Create a simile, metaphor, or other figure of speech to help you remember #1 and #2. • What affect does horizontal velocity have on the vertical velocity?

  8. Horizontal and vertical velocities are ____of each other.

  9. You always need to find the time. . . . Special equation to find time: y = vertical displacement g = - 9.8

  10. Horizontal and vertical velocities (are / are not ) INDEPENDENT of each other.

  11. The ( horizontal / vertical ) velocity of a projectile is constant. The ( horizontal / vertical ) velocity of a projectile is accelerated.

  12. Let’s practice! 1. A diver runs off the end of the diving platform at 3.2 m/s. He hits the water 1.07 seconds after leaving the platform. How high is the platform?

  13. Horizontal and vertical velocities are (DEPENDENT / INDEPENDENT ) of each other.

  14. A projectile is only affected by ________.

  15. The vertical velocity of a projectile is ( constant / accelerated ). The horizontal velocity of a projectile is ( constant / accelerated ).

  16. Let’s practice! 2. A stunt car drives off a 12 meter tall cliff. It lands 23 meters away from the base of the cliff. With what speed did the car leave the cliff? 12 m = y 23 m = x Vx=? a = -9.8m/s/s
