Introduction: 7.1 The moment of Inertia has multiple formulas according to the object that is being measured. Dependent on the type of object and whether it is hollow or solid. Even if these objects were to have the same mass or the same outside shape they would not reach their destination at the same speed if dropped on a slope. When using these rigid bodies the kinetic energy would be different from the normal (1/2)mv^2, but half times mass times speed of the center of mass squared plus half times the moment of inertia times angular speed squared. The mechanical energy is conserved in the rigid body and there is no kinetic friction. Only gravity is present. 7.2 When doing an experiment finding the moment of inertia we use the formula torque/angular

Unformatted text preview: acceleration, where torque equals the length of the vector to the point of the force times the force. When hanging from a string torque would be radius times Tension or radius times mass time (gravity minus acceleration. With this the moment of inertia equals mass times r squared times (gravity over radius time angular acceleration. .minus one). Results: Conclusion: This experiment shows how to accurately measure the rotations of various rigid-bodies using a ramp and how to accurately measure moments of inertia of these rigid-bodies. It clearly explains the difference between linear motion and angular motion....
