Concept of Force
Go to the previous , next chapter. Types of Stretching How to Stretch : next chapter Flexibility : previous chapter Just as there are different types of flexibility, there are also different types of stretching. Stretches are either dynamic meaning they involve motion or static meaning they involve no motion. Dynamic stretches affect dynamic flexibility and static stretches affect static flexibility and dynamic flexibility to some degree. The different types of stretching are: ballistic stretching dynamic stretching active stretching passive or relaxed stretching static stretching isometric stretching PNF stretching Ballistic Stretching Dynamic Stretching Active Stretching Passive Stretching Static Stretching Isometric Stretching PNF Stretching Ballistic Stretching Dynamic Stretching : next section Types of Stretching : beginning of chapter Ballistic stretching uses the momentum of a moving body or a limb in an attempt to force it beyond its normal range of motion. This is stretching, or "warming up", by bouncing into or out of a stretched position, using the stretched muscles as a spring which pulls you out of the stretched position. This type of stretching is not considered useful and can lead to injury.
Energy , in physics , the capacity for doing work. It may exist in potential , kinetic , thermal , electrical, chemical , nuclear , or other various forms. There are, moreover, heat and work—i. After it has been transferred, energy is always designated according to its nature. Hence, heat transferred may become thermal energy , while work done may manifest itself in the form of mechanical energy. All forms of energy are associated with motion. For example, any given body has kinetic energy if it is in motion.
Mass is both a property of a physical body and a measure of its resistance to acceleration a change in its state of motion when a net force is applied. The basic SI unit of mass is the kilogram kg. In physics , mass is not the same as weight , even though mass is often determined by measuring the object's weight using a spring scale , rather than balance scale comparing it directly with known masses. An object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force, while mass is the property that along with gravity determines the strength of this force. There are several distinct phenomena which can be used to measure mass. Although some theorists have speculated that some of these phenomena could be independent of each other,  current experiments have found no difference in results regardless of how it is measured:.
Types of Forces
Force is the external agent that produces motion or tends to produce motion or it stops motion or tends to stop motion. Basically, there are two types of forces, contact forces, and non-contact forces. Gravitational forces, electric forces, magnetic forces, nuclear forces, frictional forces are some examples of force. This Post also Includes a Lot of:. Keep Reading. A force that moves or tends to move stops or tends to stop the motion of the object.
A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. Previously in this lesson , a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects. These types of individual forces will now be discussed in more detail. To read about each force listed above, continue scrolling through this page. Or to read about an individual force, click on its name from the list below. An applied force is a force that is applied to an object by a person or another object.
Different types of forces with Examples in Physics
It is of course, the product multiplication of mass of the particle and its acceleration. Force is the manifestation of action of one particle on the other. It is a vector quantity. A Force has following basic characteristics. Force is represented as a vector.
Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction. When two entities come in contact with each other. You know the many different things that force can do.
Вы немец. Мужчина нерешительно кивнул. Беккер заговорил на чистейшем немецком: - Мне нужно с вами поговорить. Мужчина смотрел на него недовольно. - Was wollen Sie.
Стратмор полагал, что у него еще есть время. Он мог отключить ТРАНСТЕКСТ, мог, используя кольцо, спасти драгоценную базу данных. Да, подумал он, время еще. Он огляделся - кругом царил хаос.
