Inertial Mass

Mr. Anderson explains inertial mass in AP Physics Essentials video 9. He discusses how astronauts measure their mass in space using a spring-based device, contrasting inertial mass with gravitational mass. The video includes a physics lab experiment using a modified Atwood machine to demonstrate the relationship between net force, inertial mass, and acceleration. Newton's second law is applied to understand these concepts, emphasizing the indirect relationship between mass and acceleration when force is constant.
