What is work a product of?
Work is the product of the force on an object and the distance through which the object is moved. Work is done when a force acts on an object and the object moves in the direction of the force.
How is work defined?
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. To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd.
Why work is so called the product of force?
In other words, work is equal to the magnitude of an object’s displacement while an external force is applied to the object multiplied by the magnitude of the component of the external force which is along the displacement. …
Why is work a dot product?
A dot product is where you multiply one vector by the component of the second vector, which acts in the direction of the first vector. It’s two vectors multiplied together. But more specifically it’s the force acting in the direction you’re moving, multiplied by the displacement. This is why work is a dot product.
Is work product one word?
Often stated as the work-product doctrine1 or even the work-product rule. Further, some present the privilege using a hyphen, as in attorney-work product.
What is the best definition of work?
1 : activity in which one exerts strength or faculties to do or perform something: 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.
Which of the following is definition of work?
Work is defined as the force in the direction of displacement times displacement. It is a scalar quantity having S.I unit Joule. W=Fs.
What is the definition of work in chemistry?
In physical science, such as physics and chemistry, work is force multiplied by distance. Work occurs if there is movement in the direction of the force. The SI unit of work is the joule (J). This is the work expended by a force of one newton (N) over a displacement of one meter (m).
What is the product of force?
In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement.
What is defined as the product of the force applied to move an object and the displacement in the direction of the force?
Work is the transfer of energy by a force acting on an object as it is displaced. The work W that a force F does on an object is the product of the magnitude F of the force, times the magnitude d of the displacement, times the cosine of the angle θ between them.
Is work a dot product or cross product?
Work is the dot product of force and displacement. Torque is the cross product of the moment arm and the force.
How does the dot product work?
In mathematics, the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number. Algebraically, the dot product is the sum of the products of the corresponding entries of the two sequences of numbers.
