Projectile Motion: Launching Things into the Air


Chapter 2 section 4
October 5, 2010HW: 2.4 PTG #1-7, Skip 4, Due ThursdayP/T Conferences: Oct. 6-7, 4-7:30pm . Report Cards will be given at conferences

  • Do Now:

    • WDYS/WDYT

      • Pg. 174

  • Agenda:

    • Do Now

    • LO/SC

    • 2.4 Investigate pg. 174-176

  • Learning Objective:

    • Compare horizontal motion to vertical motion in projectile motion

  • Success Criteria:

    • Apply the terms free fall, projectile, trajectory, and range

    • Provide evidence concerning projectiles launched horizontally from the same height at different speeds (including zero launch speed)

    • Explain the relationship between the vertical and horizontal components of a projectile’s motion

Chapter 2 section 4
October 6, 2010 ProjectileHW: 2.4 PTG #1-7, Skip 4, Due ThursdayP/T Conferences: Oct. 6-7, 4-7:30pm . Report Cards will be given at conferences

  • Do Now:

    • Describe what would happen if you dropped a bowling ball and a marble from the same height.

  • Agenda:

    • Do Now

    • LO/SC

    • Physics Talk

    • Quiz

  • Learning Objective:

    • Compare horizontal motion to vertical motion in projectile motion

    • Explain the impact of gravity in free falling objects

    • Explain how initial velocity and the angle of velocity impact the range of an object with projectile motion

  • Success Criteria:

    • Apply the terms free fall, projectile, trajectory, and range

    • Provide evidence concerning projectiles launched horizontally from the same height at different speeds (including zero launch speed)

    • Explain the relationship between the vertical and horizontal components of a projectile’s motion

    • Recognize the factors that affect the range of projectiles

    • Infer the shape of a projectile’s velocity.


2 4 physics talk
2.4 Physics Talk Projectile

  • What is a projectile?

  • What happens to two objects that are dropped at the same time if there is little/no air resistance?

  • An object traveling through the air

  • They will hit the ground at the same time


2 4 physics talk1
2.4 Physics Talk Projectile

  • Does the horizontal motion of the object affect the time it hits the floor?

  • No! Horizontal motion and vertical motion are independent of each other!


2 4 physics talk2
2.4 Physics Talk Projectile

  • What happens to velocity with projectiles?

  • Horizontal velocity remains the same!

  • Vertical velocity is constantly changing (acceleration due to gravity)

  • Horizontal and vertical velocity can be combined to predict the range of a projectile.
