no
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%
The work system refers to the system in which either the human beings or the machines participate.
sort of trajectory, solutions of eqaution of motion of a mechanical system,
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.
No you still do the same amount of work
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
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.
Work done by the system is considered as PositiveWork done on the system is considered as Negative
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.
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: when a surrounding does work on the system the total energy increases so work done is positive..........
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.

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.
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.
work
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.
