## Projectile motionPresentation Transcript

• Guide Questions What is projectile motion?What are the two (2) cases of projectile motion? How do they differ from each other?
• Guide Questions What factors affect the motion of a projectile? How do these factors affect a projectile?Is a projectile a free falling body? Explain.
• Important Terms Projectile motion – a combination of vertical and horizontal motions that are completely independent of each otherProjectile – an object or body thrown with an initial velocity and whose motion is influenced by the pull of gravity
• Important Terms Trajectory – the curved path of a projectile; it is principally determined by two types of motion: vertical and horizontal motionsRange (dx) – the horizontal displacement of a projectile
• Important Terms Height (dy) – the vertical displacement of a projectile
• Cases  Projectile I: Body Launched Horizontally (θ= 0°)
• Cases  Projectile II: Body Launched at a Certain Angle (90°>θ> 0°)
