when work is done on a system by an external force, the system?

When work is done by an external force, the system will have more energy in it than it did before.

If a system as a whole exerts a force on its surroundings and a displacement occurs, the work done is called external work. A physics teacher pushing papers across his desk is doing external work. A physics teacher standing motionless is not doing any significant external work.

What is the relationship between heat added to a system and the internal energy and external work done by the system-?
When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
What is work done by a force in a mechanical system called?
Such work - the product of force and a distance - is simply called "work". It is actually a kind of energy.
Do all forces of an object cause work to be done?
If a force is applied, but nothing in the system moves, no work has been done. Work is only done when something moves.
What is the definition of the word 'work' in physics?
The word 'work' in physics is defined as the transfer of energy from one material body to another. It is a body's displacement in space caused by an external force resulting in motion. If a force is applied but there is no displacement or motion, then no work is done. Also work is not done if a force is applied perpendicular to the body's displacement. Work is expressed in units such as joules or foot-pounds.
Work is done when a force is used to?
Work is done when force is used to be approximately constant
Is there work done when an asteroid moves in space with the absence of external force?
Work is equal to Force x Distance. If no force is applied, no work is done.

If you push a box forward and the box moves forward you have done how much work?
You have only done as much external work on the box as the distance it moves: work = force x distance. If it does not budge no work is done on the object. You have done "internal" work on your muscles which converts to heat energy, but technically speaking, no external work is done on the object

What the realationsip between work and mechanical energy?
I think it helps to think - informally - of work as the "transfer of energy". Work is said to be done when you apply a force along a certain distance; and energy is required to do this work. The work done on the system may increase the system's potential energy, or - if done against a force of friction - it may increase its heat energy.
When a book falls from a shelf to the ground without anyone pushing on it no work is done on the book.?
false

When force and motion are going in the same direction is work being done?
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
How can work be done?
Work done when force moves an object.
What is the work done for a force which is applied gradually?
Work = Force x Distance. So as you gradually apply the force, the work done is gradually increased.
