What is work done?
Work done is used as a term to communicate that a predetermined task has been completed OR to specifify a percentage of the task completed by saying that work done is at (f.i.) 70%
What is mean work performed?
Mean work performed refers to the average amount of work done by a system or agent over a specified period or under specific conditions. It is typically calculated by taking the total work done and dividing it by the number of instances or time intervals in which that work was performed. This concept is often used in fields like physics and engineering to assess the efficiency and output of processes or machines.
Definition of work system?
The work system refers to the system in which either the human beings or the machines participate.
What is relative equilibrium?
sort of trajectory, solutions of eqaution of motion of a mechanical system,
How does Thermodynamics affect the work of mechanical engineers?
thermodynamics, is essential for mechanical engineers, because the subject is mainly about heat and work in system, and as an engineer that is important, especially when you have to design engines, because that is when you have to determine important factors such as the amount of work that can be done by that engine internally, and the heat it transefered and obtained.
A energy is?
Energy is the potential to do some work. If there is work done on a system, this work done is stored as potential energy of the system. If the system in motion, it should have kinetic energy. Hence total energy of the system PE+KE
What is the work done by the system according to the sign convention?
The work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system by the surroundings.
When force and motion are going in the same direction is work being done?
Yes, work is being done when force and motion are going in the same direction. Work is defined as the product of force applied in the direction of motion and the distance over which the force is applied. So, when force and motion are in the same direction, work is being done.
Is the work done by the system is considered as positive or on the system is considered as positive?
Work done by the system is considered as PositiveWork done on the system is considered as Negative
Can work be done if there is no motion?
Yes, work can still be done even if there is no motion. Work is defined as the force applied over a distance, so as long as there is a force acting on an object in the direction of the force, work is being done. If an object is stationary but has a force applied to it, work is still being done even though there is no motion.
Work done on the system is?
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
What is the relationship between the work done on the system and the work done by the system in a thermodynamic process?
In a thermodynamic process, the work done on the system is equal and opposite to the work done by the system. This is based on the principle of conservation of energy, where the total work done in a closed system remains constant.
When force is perpendicular to the direction of motion is work done?
No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.
What is the relationship between the work done on a system and the work done by a system in a thermodynamic process?
In a thermodynamic process, the work done on a system is equal and opposite to the work done by the system. This is known as the principle of conservation of energy.
When the force acting on an objects points at least partially in the blank direction of the motion the work done is considered to be what?
When the force acting on an object points at least partially in the direction of motion, the work done is considered to be positive. This is because the force is helping to move the object in the same direction as its motion, resulting in a positive work output.
When force is perpendicular to the direction of motion no work is done ture or false?
True. When the force is perpendicular to the direction of motion, no work is done because work is the product of force and displacement in the direction of the force. Since there is no displacement in the direction of the force, no work is done.
When a force changes the motion of an object what is done?
work
