Rotational Motion OBJECTIVE:By applying known torques to a system which is free to rotate, the resulting angular acceleration will be measured and used to determine the moment of inertia of the system. SREE KOLACHANA PHYSICS I- 1410L SECTION:806 SUNIP MUKHERJEE 12/05/2017 ASHLEYCRONAN

PAGE 2 The moment of inertia of a rigid body depends on the way in which it’s mass is distributed relative to the axis of rotation. Such a body can be thought of as made up of a very large number of elemental masses and the total number moment of inertia is then the sum of contributions from all such masses (Image II). If mirepresents the mass of one such element located at a distance ri, from the axis, then the total moment of inertia would be: I=𝒎𝒊∗ 𝒓𝒊??𝒊=?----------------------------------------------------------------------------------------------------------------------------(2)
