October 6, 2010 HW: 2.4 PTG #1-7, Skip 4, Due Thursday P/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 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 Talk 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 Talk 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.
