Understanding why distance is area under velocity-time line. Created by Sal Khan.
In this lesson, students will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different control surfaces. The goal of this lesson is for students to apply their existing knowledge about the four forces affecting flight and apply engineering design to develop a sound glider. They will also communicate the reasoning and results of any design modifications made.
Worked examples finding displacement and distance from position-time graphs.
This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.
