What is work Wiki?
Work (human activity), intentional activity people perform to support themselves, others, or the community. Manual labour, physical work done by humans. House work, housework, or homemaking.
Whats the definition of work in physics?
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.
What is the simple definition of work?
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 work work and energy?
Energy. Work is defined as transferring energy into an object so that there is some displacement. Energy is defined as the ability to do work. Work done is always the same.
What is net work physics?
Net work is defined to be the sum of work done by all external forces—that is, net work is the work done by the net external force . In equation form, this is where. is the angle between the force vector and the displacement vector.
What is work in physics class 9?
Class IX Science Work Done. • 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.
What is work in physics class 11?
In Physics, work is defined as the product of force and displacement. If an object is acted upon by a force, work done is nothing but the product of the magnitude of this force and the displacement of the object caused by the force.
What is the best way to define work?
Define work. The result of using force to move an object over a distance. Unit of measure for distance.
What causes work physics?
There are three key ingredients to work – force, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.
How do you find work physics?
The formula for calculating work is Work = Force x Distance . Hence, to calculate the distance from force and work, proceed as follows: Determine the work done, W , when the force, F , is applied. Divide the work done, W , by the applied force, F .
What is work class 9 short answer?
Work is said to be done when a force causes displacement of an object in the direction of applied force. Q2. Write an expression for the work done when a force is acting on an object in the direction of its displacement. Q3.
What is work and its types?
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.
