Projectile Motion

Predict the full flight: treat horizontal and vertical motion separately, then combine results correctly.

This topic includes

Subtopics to master

Time, height, and range — plus the reasoning that prevents common mistakes.

Timing
Time of Flight
Use vertical motion to determine how long the projectile stays in the air.
  • Same launch/landing height cases
  • Different landing height cases
  • Key conditions & assumptions
Start subtopic Vertical motion sets the time.
Peak
Maximum Height
Find the peak by using v_y = 0 and constant-acceleration vertical motion.
  • Using v_y = 0 at the top
  • Height above launch point
  • Energy vs kinematics comparison
Start subtopic Clean, repeatable method.
Distance
Range
Combine time of flight with horizontal speed to get horizontal distance traveled.
  • R = v_x · t approach
  • Angle dependence intuition
  • Common traps & units
Start subtopic Combine x + y correctly.
Practice
Practice & Exercises
Train time/height/range workflows with mixed scenarios and “common mistake” traps.
  • Decompose (v0, θ) into components
  • Time-of-flight mixed sets
  • Max-height problems
  • Range problems (same/different heights)
  • Exam-style multi-step projectiles
