SCI - Lesson 1

• projectile motion - form of two dimensional motion
• Projectile - Any object which projected by some means and continues to move due to its own inertia (mass).
• Conditions of Projectile Motion

  ■ Throughout the Flight

  ■ Along the Horizontal

  ■ Along the Vertical

  ■ When the vertical displacement is at its Maximum
• Types of Projectiles

  ❑ Type I

  ❑ Type II

  ❑ Type III
• Type I projectile - objects dropped from rest
• Type II projectile - objects that are thrown vertically upward
• Type III projectile - Objects thrown upward at an angle to the horizontal
• projectile - an object that is initially thrown into the air and continues to move on its trajectory acted upon gravity
• three factors that are important in projectile motion

  • time of flight

  • range

  • maximum height
• time of flight - the entire duration while the projectile is in its trajectory
• range - maximum horizontal distance traveled by the projectile
• maximum height - the maximum vertical displacement traveled by the projectile in it’s trajectory
• trajectory - parabolic path produced by two components
