How is work related to the conservation of mechanical energy?
Work equals the change in energy, in a closed system energy is not lost. So in a closed system any work done will be countered by an equal and opposite work. An example is throwing a ball up into the air and catching it again. The work done by you to accelerate it is equal and opposite to the work done by the earth.
Conservative Nature of induced electric field?
The conservative nature of induced electric field is due to time varying magnetic fields. This occurs because the work done in moving a charge in a closed path in this field is not zero.
What is the work done by a body moving along a circular path?
i think it is zero
When do you say work is done?
Work done is zero when a body moves up a hill or climb an object and then descend. In moving a body Q from point B to a point A along a path X, a work is done which is equal to the potential energy gained by the body. If the body then goes back from A to B along a path Y, it loses the potential energy gained and so the total work done on the body becomes zero.
A rock moves in a straight path in space with a constant speed.is there any force acting on the rock.is there any work done when the rock moves?
There is no force acting and therefore no work done.
When is work done though displacement is zero?
When an object is propelled by a non-centripetal force through a closed path.
When an object moves circular path what is the work done specify reason?
Zero work done
What cause a series circuit to work and not work?
A series circuit will work if there is a closed path through which the current can pass, and a voltage source. Otherwise it won't.

Is any work is done while sleeping?
you are breathing and you are keeping your eyes closed
What is made up of parts that work together to form a complete path allowing electricity to flow?
A closed electrical circuit.

What is the correct sentence you have done a lot of work on this new software project or you have done much work on this new software project?
You have done much work on this new software project
What is the unit for measuring work?
if the work is done in a straight path than Work = Force x Distance (otherwise w=FDcos(theta) ) The units of work is the joule.
A rock moves in a straight path in space with a constant speed.is there any force acting on the rock.is there any work done when the rock moves?
There is no force acting and therefore no work done.
