These are two extremes on the pendulum-course that is audience; the former is too narrow of an audience, while the latter is too broad. Therefore, it is important for the student to articulate an audience that falls somewhere in between.
The system of non linear equations for the damped pendulum can be written as: \dot X = Y \dot Y = -y-sin x Using V (x, y) = 1/2 Y^2 + (1-cos (x)) show the original as a stable critical point. A pendulum swings back and forth, hanging from a cable. (Treat it like a massless string.)

There are three phases in audience analysis. The first is adapting to your audience before you speak. There are three ways to do this: demographic analysis, attitudinal analysis, and environmental analysis. Demographic analysis involves age, gender, culture, ethnicity, race, religion, and educational level.
3 categories of the audience are the lay audience, managerial audience, and expert audience.
What are the five types of Audiences? Pedestrian, passive, selected, concerted, and organized audience.
In live event environments, we've come to know four different audience types:The Spectator: An audience member in the classic sense, a spectator is someone who comes to watch a performance or presentation but not actively participate. ... The Participant: ... The Spy: ... The VIP:
The intended audience effects all aspects of a publication. The subjects covered are chosen with an audience in mind. Contributors are hired based upon how well they could possibly connect with the desired audience.
This group includes attributes, such as age, income, education, gender or geographic location. Using demographic data you can target your campaign for example at young people (eg. age 18-24), both female and male from towns with a population larger than 20,000.

The form of potential energy possessed by a pendulum bob is gravitational potential energy. The amount of gravitational potential energy is dependent upon the mass ( m) of the object and the height ( h) of the object. The equation for gravitational potential energy ( PE) is.
There are two dominant forces acting upon a pendulum bob at all times during the course of its motion. There is the force of gravity that acts downward upon the bob. It results from the Earth's mass attracting the mass of the bob. And there is a tension force acting upward and towards the pivot point of the pendulum.
As the string is lengthened, the period of the pendulum is increased. There is a direct relationship between the period and the length. Finally, the experimenters investigated the possible effect of the arc angle upon the period in trials 4 and 10-13.
Two types of potential energy are discussed in The Physics Classroom Tutorial - gravitational potential energy and elastic potential energy. Elastic potential energy is only present when a spring (or other elastic medium) is compressed or stretched. A simple pendulum does not consist of a spring.
So there is a net force directed along the other coordinate axes. It is this tangential component of gravity which acts as the restoring force. As the pendulum bob moves to the right of the equilibrium position, this force component is directed opposite its motion back towards the equilibrium position.
In physical situations in which the forces acting on an object are not in the same, opposite or perpendicular directions , it is customary to resolve one or more of the forces into components. This was the practice used in the analysis of sign hanging problems and inclined plane problems.
Earlier in this lesson we learned that an object that is vibrating is acted upon by a restoring force . The restoring force causes the vibrating object to slow down as it moves away from the equilibrium position and to speed up as it approaches the equilibrium position.
Audience knowledge of a topic can vary widely on any given occasion, therefore, communicators should find out what their audience already knows about the topic . Never overestimate the audience’s knowledge of a topic. If a speaker launches into a technical discussion of genetic engineering but the listeners are not familiar with basic genetics, they will be unable to follow your speech and quickly lose interest. On the other hand, drastically underestimating the audience’s knowledge may result in a speech that sounds condescending.
Audience analysis involves identifying the audience and adapting a speech to their interests, level of understanding, attitudes, and beliefs. Taking an audience-centered approach is important because a speaker’s effectiveness will be improved if the presentation is created and delivered in an appropriate manner. Identifying the audience through extensive research is often difficult, so audience adaptation often relies on the healthy use of imagination.
The demographic factors of an audience include age, gender, religion, ethnic background, class, sexual orientation, occupation, education, group membership, and countless other categories. Since these categories often organize individual’s identities and experiences, a wise speaker attends to the them. Politicians usually pay a great deal of attention to demographic factors when they are on the campaign trail. If a politician speaks in Day County, Florida (the county with the largest elderly population) they will likely discuss the issues that are more relevant to people in that age range – Medicare and Social Security.
The setting of a presentation can influence the ability to give a speech and the audience’s ability and desire to listen. Some of these factors are: the set-up of the room (both size and how the audience is arranged), time of day, temperature, external noises (lawn mowers, traffic), internal noises (babies crying, hacking coughs), and type of space (church, schoolroom, outside). Finding out ahead of time the different factors going into the setting will allow a speaker to adapt their speech appropriately. Will there be a stage? Will there be a podium or lectern? What technology aids will be available? How are the seats arranged? What is the order of speakers?
Audiences are either voluntary, in which case they are genuinely interested in what a presenter has to say, or involuntary, in which case they are not inherently interested in the presentation. Knowing the difference will assist in establishing how hard a speaker needs to work to spark the interest of the audience. Involuntary audiences are notoriously hard to generate and maintain interest in a topic (think about most people’s attitudes toward classes or mandatory meetings they would prefer to not attend.)
A simple pendulum is a mechanical arrangement that demonstrates periodic motion. The simple pendulum comprises a small bob of mass ‘m’ suspended by a thin string secured to a platform at its upper end of length L.
The oscillatory motion of a simple pendulum: Oscillatory motion is defined as the to and fro motion of the pendulum in a periodic fashion and the centre point of os cillation known as equilibrium position.
Kinetic Energy. The kinetic energy of the pendulum is given as K.E = (1/2) mv 2. At the highest point, the kinetic energy is zero and it is maximum at the lowest point. However, the total energy is constant as the function of time.
A simple pendulum is an idealized model. It is not achievable in reality. But the physical pendulum is a real pendulum in which a body of finite shape oscillates. From its frequency of oscillation, we can calculate the moment of inertia of the body about the axis of rotation.
However, the movement of the pendulum is not free fall it is constrained by the rod or string. The height is written in terms of angle θ and length L. Thus, h = L (1 – cos θ)
One force is gravity . The force of gravity acts in a downward direction and does work upon the pendulum bob.
Tension is an external force and if it did do work upon the pendulum bob it would indeed serve to change the total mechanical energy of the bob. However, the force of tension does not do work since it always acts in a direction perpendicular to the motion of the bob.
You need to remember that there are two forces acting on the pendulum: (1) Gravity toward the earth, and (2) Tension toward the center of the circle formed by the arc that the pendulum describes. If gravity is resolved into a vector perpendicular to the arc, and a vector tangential to the arc, the tangential component is a restoring force ...
As the pendulum swings through its arc, the restoring force tries to bring it back to dead center. At dead center, the pendulum has reached its equilibrium position, and velocity is constant. That's why the acceleration vector ceases to have any direction other than toward the pivot at dead center. At dead center, centripetal acceleration is ...
