PHY 1322 Study Guide - Small-Angle Approximation, Kolmogorov Space, 1Time Airline
Document Summary
The purpose of this lab is to determine the gravitational acceleration g, with an uncertainty of less than rigid pendulum equation and the parallel axis theorem. The gravitational acceleration will be determined using the. For any rigid body with small oscillations (q< 5%(cid:176) ) about a fixed horizontal axis, the period may be determined using the equation: I= moment of inertia about the axis of oscillation in (kg*m2) M= mass of the body (kg) h= distance between the center of gravity and the axis of oscillation (m) g= gravitational acceleration (m/s2) The moment of inertia can be determined using the moment of inertia of the pendulum about an axis through the center of gravity parallel to the axis of oscillation (i0), and the theorem of parallel axes. To find i0, a comparison between the period of oscillation of the pendulum and the period of oscillation of a bar suspended from the same wire will be made:
