1)Bozeman Science: Newton’s 3 Laws of Motion: Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch. (For Students and Teacher) 2) Bozeman Science: Free Body Diagrams: Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems. (For Teacher) 3)Mocomi Kids: What is Inertia: Newton’s Laws: Inertia is explained using examples and definitions. (For students) 4)Bozeman Science: Next Generation Science Standards Physical Science Disciplinary Core Idea 2A: Forces & Motion Paul Andersen introduces forces, motion, and Newton's three laws in this video. He begins by describing forces as pushes or pulls on objects that produce motion. A lack of motion results from a balanced set of forces. A teaching progression K-12 is also included. (For Teacher) 5)Rhett Allain: Two fans with Same Force and Different Mass This is a short video that demonstrates the relationship between Force and Mass as well as the resulting acceleration in two different scenarios. 5)Newton’s 1st Law: Image from thinglink.com Kicking a soccer ball to demonstrate Newton’s 1st Law 6)Newton’s 1st Law: Image from NASA Applied to the launching of Rocket 7)Acceleration vs. Force Graph: Image from BBC Slope of the line is the mass. Demonstrates the proportional relationship between force and acceleration 8)Kicking two masses with the same force: Image from Learn Parallax.com This image demonstrates the relationship between force and mass. The same force applied to 2 different masses.
Students will further evaluate factors that affect the motion of an object. In this lesson, students will analyze the relationship between the force, mass, and acceleration. The primary focus of this lesson will be the relationship between force and mass in the context of causing an object to accelerate. This lesson is a continuation of the S8P3.a and S8P3.b with a narrowed focus that relates Newton’s 1st and 2nd Law to the motion of an object.
