Sammie G Course# PHYS 1410L Section# - 815 TA: Ankur Roy 4/19/18 Partners: Lilly H Rotational Motion Objective : From the knowledge of applied torque angular acceleration is measured, from which the momentum of inertia of the system
Introduction Theory: When an object is spinning it should follow Newton linear law F = ma but if object is “rigid”, meaning its deformation is zero or so close to zero that it can be neglected but will be converted to angular motion τ = since the object is spinning. The idea of the experiment is to determine the momentum of inertia of a system. Equation: I = i = 1 n m i v i 2 The total moment of inertia is I. m i is the mass. v i is the initial velocity. I thy = 1 2 m R 2 this equation is the theoretical moment of inertia. M is the mass R is the radius τ = + τ f This is the equation for torque. Torque is τ , I is moment of inertia, α is angular accretion and toque is τ f diff = | I exp I thy | I thy × 100 this equation is how to find the percent error rate.
