We have described a simple pendulum as a point mass and a string. A physical pendulum is any object whose oscillations are similar to those of the simple pendulum, but cannot be modeled as a point mass on a string, and the mass distribution must be included into the equation of motion.

Use a simple pendulum to determine the acceleration due to gravity \(g\) in your own locale. Cut a piece of a string or dental floss so that it is about 1 m long. Attach a small object of high density to the end of the string (for example, a metal nut or a car key).

2023年5月2日 · A pendulum is a string hanging from a fixed spot with a weight (called a bob) at one end that can swing back and forth. One day in the late 1500s, a budding scientist named Galileo Galilei was sitting in church when he noticed the chandeliers hanging from the ceiling were swinging back and forth.

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 16.13. 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 ...

I will be investigating the effect of the length of a pendulum’s string on the time for the period of that pendulum. Given my previous knowledge, I know that a pendulum behaves in an oscillating manner, meaning that the acceleration is always proportional to the negative distance.

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, the strength of gravity, and the amplitude of the swing. Observe the energy in the system in real-time, and vary the amount of friction. Measure the period using the stopwatch or period timer.

A simple pendulum consists of a relatively massive object hung by a string from a fixed support. It typically hangs vertically in its equilibrium position. The massive object is affectionately referred to as the pendulum bob .

A physical pendulum is any object whose oscillations are similar to those of the simple pendulum, but cannot be modeled as a point mass on a string, and the mass distribution must be included into the equation of motion.

A pendulum consists of a weight that must travel on a circular arc that is determined by the length of the string. It swings back and forth; it is also a little higher at the ends of the swing than it is at the middle.
