What is the work explain?
work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
What is work and example?
Work is force applied over distance. Examples of work include lifting an object against the Earth’s gravitation, driving a car up a hill, and pulling down a captive helium balloon. Work is a mechanical manifestation of energy. The standard unit of work is the joule (J), equivalent to a newton – meter (N · m).
What is the best definition for work?
a : activity that a person engages in regularly to earn a livelihood people looking for work. b : a specific task, duty, function, or assignment often being a part or phase of some larger activity. c : sustained physical or mental effort to overcome obstacles and achieve an objective or result.
What is work equal to in physics?
Physicists provide an exact mathematical definition of their notion of work. In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
What is meant by work answer?
Answer: Work is defined as displacement of any body in the direction of applied force . Calculated as the product of Force and displacement . S.I Unit is Joule .
What is work class 11?
When a force acts on an object and the object actually moves in the direction of force, then the work is said to be done by the force. Work done by the force is equal to the product of the force and the displacement of the object in the direction of force.
What is the importance of work?
For individuals, work is an important feature in structuring: personal and social identity; family and social bonds; ways of making money, and thereby accessing a number of essential and non-essential goods, services and activities; daily routines; level of activity; physical and mental well-being; self-confidence and.
What are the types of work?
Types of Working Patterns Standard work. This is a very traditional work pattern of Monday – Friday 9.00am – 5.00pm with a lunch break in the middle. Flexible work. Many employees work flexible hours. Shift working. Agency work. Freelance work. Working for yourself.
What is work and power?
Work is the displacement of an object when a force (push or pull) is applied to it. We define the capacity to do the work as energy. Power is the work done per unit of time.
What is work in your own words?
Work is physical or mental effort in order to produce or accomplish something. Work is an occupation or something that someone does or has done. An example of work is a job as an accountant. An example of work is someone having plumbing done at their house.
What is the other word for working?
What is another word for working? employed salaried in work at work in gainful employment in a job active busy in harness occupied.
What is the state meaning of working?
1 : engaged in work especially for wages or a salary a working journalist a working mother. 2 : adequate to permit work to be done a working majority. 3 : assumed or adopted to permit or facilitate further work or activity a working draft. 4 : spent at work working life.
What is work in Brainly?
Answer: Work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force.
What is work in physics class 9?
• Work done on an object is defined as the magnitude of the force multiplied by the distance moved by the object in the direction of the applied force. Work done = force × distance. = F × s.
Is work an energy?
In physics, work is the energy transferred to or from an object via the application of force along a displacement. Work transfers energy from one place to another, or one form to another. The SI unit of work is the joule (J), the same unit as for energy.
What is work and its type?
Work is a scalar quantity and is the product of two vector quantities. Depending on the value of q, there are three types of work: When q = 0°, work is said to be positive. Stretching of the spring is an example of positive work as the force is acting in the direction of displacement of the spring.
What is work its unit?
The SI unit of work is joule (J). Joule is defined as the work done by a force of one newton causing a displacement of one meter. Sometimes, newton-metre (N-m) is also used for measuring work.
What is work and write its formula?
We define work to be equal to the product of the force and the displacement. Work done = force × displacement. W = F × s. 1J=1N×1m.
What is work class 9 short answer?
Work is done whenever the given conditions are satisfied: → A force acts on the body. → There is a displacement of the body caused by the applied force along the direction of the applied force. Write an expression for the work done when a force is acting on an object in the direction of its displacement.
What is work BYJU’s?
The SI unit of work is the joule (J), which is defined as the work done by a force of 1 Newton in moving an object through a distance of 1 meter in the direction of the force. Here, the work done upon the barbell is against gravity.
What is meant by 1 Joule work?
joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
