Question

Physics 1032, Section 601 Worksheet #1 January 23, 2019 A BASIC PENDULUM Consider a pendulum with a length L 1.00 m and a mass m 0.50 kg attached at the end of it. At time i Ξ Ο 00 s, the pendulum has a deflection θ ores eo 0.080 rid. The velocity v of the mass is v 0.00 rad/sec. (The abbreviation rad stands for radians, Angles can be measured in degrees or radians. The conversion factor is 2 radians = 360 degrees.) Ignore friction for this example When the pendulum is released, it oscillates back and forth with a period T and frequency f @ 0 ーー vertice What is the definition of the period of an oscillation? I. 2 Calculate the period T of this pendulum. 3. What is the definition of the frequency f of an oscillation? 4 Calculate the frequency f of the oscillations of the pendulum.

Answer 1

Time period (T): - It is the time required to complete one oscillation T = 2 pi squareroot e/9 = 2 pi squareroot 1/9.81 T = 2.00 s Frequency (f): - No. of oscillators completed in one second f = 1/T = 1/2 f = 0.5 H_z
