The Four Forces of Flight Worksheet
A printable science worksheet for grades 4-6 on the four forces of flight. Students read a one-page passage on thrust, drag, gravity and lift, and on the three control surfaces a pilot actually steers with, then answer four multiple-choice questions, six true-or-false statements, and six fill-ins. A complete answer key is included.

Learning Objective
Students will name the four forces of flight, explain how each one acts on an airplane, and identify the three control surfaces a pilot uses to steer.
Lesson Overview
About this worksheet
Every airplane in the sky is balancing four forces at once. Thrust pushes it forward, drag pushes back, gravity pulls it down, and lift holds it up. Whether a plane climbs, dives, speeds up or slows down is entirely a question of which force in each pair is winning, and this worksheet is built around that idea rather than around four definitions to memorize.
Lift gets explained twice, on purpose. A wing is curved on top and meets the air at a slight angle; air moves faster over the top than underneath, faster air presses less hard, and the higher pressure below pushes the wing up. The second way of saying it is the one a student can picture: the wing throws air downward, and pushing air down pushes the wing up. Both are true and they describe the same event.
The worksheet also gets the controls right, which many introductions do not. Ailerons sit near the back of each wing and roll the plane into a bank. Elevators are at the tail and point the nose up or down. The rudder is on the upright tail fin and swings the nose left or right. Ailerons roll, elevators pitch, the rudder yaws — and a pilot turning properly uses more than one together.
Page 2 asks sixteen questions in three forms. Page 3 is a complete answer key with a short reason beside every false statement. Pair it with the Gravity Worksheet or Balanced and Unbalanced Forces for the wider physics.
How to Use This Lesson
Read the passage on page 1.
Answer the four multiple-choice questions in Section A.
Mark each Section B statement TRUE or FALSE, and be ready to say why.
Write the missing word in each Section C sentence.
Use the answer key on page 3 for self-check or grading.
Discuss what a pilot must arrange for the plane to descend and land.
