I can use projectile patterns to select a launch condition and explain tradeoffs in accuracy and range.
POE Unit 4 • Lesson 4.12
Launch Angle, Range, and Mission Requirements
Focus question: How do launch angle and speed interact with a target-range requirement?

What You Will Be Able to Do
Launch-angle prediction table
The recommendation identifies the ideal maximum-range angle, complementary-angle behavior, and a controllable way to adjust range.
Activity Flow
How the Lesson Moves
Each step builds the data, motion, or testing reasoning required for today’s deliverable.
1. Predict the trend
Compare ranges across several angles at constant speed.
2. Connect to theory
Identify complementary angles and the maximum-range region.
3. Meet the requirement
Select a controllable adjustment for a target that is too short or too long.
Lesson Interactive
Match Launch Conditions to Range
Apply the lesson concept to a mission-performance scenario. Use the feedback to correct your reasoning before completing the main deliverable.
Ideal Equal-Height Launch
30°Lower arc
45°Balanced components
60°Higher arc
Assume the same launch speed, no air resistance, and equal launch and landing heights.
Use the ideal range pattern, then choose a controllable adjustment for a shorter target.
Today’s Work
Main Deliverable
Launch-angle prediction table
Create one focused engineering artifact that demonstrates today’s learning.
- Complete a prediction table for multiple launch angles.
- Recommend an angle or speed change for a stated target and justify it.
