I can resolve launch velocity into components and describe how gravity changes each component.
POE Unit 4 • Lesson 4.11
Projectile Motion: Horizontal and Vertical Components
Focus question: How can one launch velocity be separated into independent horizontal and vertical motions?

Lesson Targets
What You Will Be Able to Do
Projectile component diagram and calculations
The component calculations use sine and cosine correctly and the top-of-flight explanation is physically accurate.
Activity Flow
How the Lesson Moves
Each step builds the data, motion, or testing reasoning required for today’s deliverable.
1. Draw the velocity vector
Mark launch speed and angle.
2. Resolve components
Calculate horizontal and vertical initial velocity.
3. Follow the motion
Describe each component at launch, at the top, and during descent.
Lesson Interactive
Resolve the Launch Velocity
Apply the lesson concept to a mission-performance scenario. Use the feedback to correct your reasoning before completing the main deliverable.
Launch Vector
Resolve the 20 m/s vector with cosine for horizontal and sine for vertical.
Today’s Work
Main Deliverable
Projectile component diagram and calculations
Create one focused engineering artifact that demonstrates today’s learning.
- Create a labeled component diagram and calculate initial vx and vy.
- Explain which component gravity changes in the ideal projectile model.
