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

Type answer...

Open Ended

What is the difference between horizontally and vertically launched projectiles?

Type response here

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
