Exploring the simple pendulum a bit further, we can discover the conditions under which it performs simple harmonic motion, and we can derive an interesting expression for its period. Pendulum experiment is important in general physics teaching. A simple pendulum is defined to have an object that has a small mass, also known as the pendulum bob, which is suspended from a light wire or string, such as shown in Figure 1. This result is interesting because of its simplicity. Thus, T 2L g T 2 L g for the period of a simple pendulum. For the simple pendulum: T 2m k 2 m mg L T 2 m k 2 m m g L. ![]() For small displacements, a pendulum is a simple harmonic oscillator. Using this equation, we can find the period of a pendulum for amplitudes less than about 15. ![]() If the bob moves away from the vertical to some angle, and is released so that the pendulum swings within a vertical plane, the period of the pendulum is given as: T 2. It is generally assumed that the mass of the string is negligible. A simple experiment with a physical pendulum examining some aspects of rigid body motion is presented in this paper. Some have crucial uses, such as in clocks some are for fun, such as a child’s swing and some are just there, such as the sinker on a fishing line. 10-12 Experiments with Charged Discs 10.13 The Electrostatic Pendulum Experiment 10-14 The Concept of. SimplePendulum PhysicsPractical Physics Experimentyou may find out this practical manual. A simple pendulum consists of a heavy pendulum bob (of mass M) suspended from a light string. Also shown are the forces on the bob, which result in a net force of − mg sin θ toward the equilibrium position-that is, a restoring force. The linear displacement from equilibrium is s, the length of the arc. A simple pendulum has a small-diameter bob and a string that has a very small mass but is strong enough not to stretch appreciably. The purposes of this experiment are: (1) to study the motion of a simple pendulum, (2) to study simple harmonic motion, (3) to learn the definitions of.
