Projectile Motion Preview

Projectiles - Objects thrown or launched into the air that are subject to gravity.

Projectiles

• Projectile Motion - Free fall with an initial horizontal velocity.

Types of Projectiles

• Projectiles launched horizontally

• Projectiles launched at an angle

Components of Projectiles

• Projectiles have two components

• x = horizontal component

• y = vertical component

Open Ended

What is the difference between horizontally and vertically launched projectiles?

​Horizontally vs. Vertically Launched Projectiles

​What is the difference?

• ​Initial vertical velocity

  • 0 m/s for horizontal

  • not 0 m/s for vertical

• Angle at which the projectile is launched
