Why a man lifting a box to be placed on a table is work?
He applied a force to the box and it moved. Force applied on it equals to the weight. As he lifts the point of application of the force gets displaced. Hence work is said to be done.
Work done in lifting and lowering an object?

How much work is done in lifting a 50kg object to height of 5m?

Is it easier to lift a 50 kilogram box straight up 8 meters or slide it up an inclined plane that is 20 meters long?
While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane. Overcoming that friction is work done which is totally wasted.While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane.

How much work is done when a 700 N refrigerator is lifted straight up a distance of 4 meters in joules?
Work is done in lifting is equal to work done in opposing gravity. Work done in opposing gravity = weight times distance = 700 x 4 =2800 joules
800 joules of work was done lifting a 200 newton box to a shelf directly above the box.?

A worker does 25 J of work lifting a bucket sets down same place What is total net work done on the bucket?
0 J
What type of work is being done when pulling?
The same type as is done when pushing, shoving, rolling, lifting, wiggling etc. ... a force acting through a distance.
If you lift two loads up one story how much work do you do compared to lifting just one load up one story?
The work done by lifting two loads up one story vs the work done lifting one load will depend on the weight of the second load. If it is the same as the first load, it would simply be twice the work to lift. Work is described as a force times a distance and a force is described as a mass times an acceleration. In this case, the force would be twice as much, so the work would be as well.
What is the relationship between work and gravitational potential energy?
Work = energy (by the Work-Energy Equivalence Theorem).The work done in lifting an object shows up as the gravitational potential energy of the object: W = mgh, where W is the work done; m is the object's mass; g is the acceleration due to Earth's gravity; and h is the height to which the object is lifted. (This assumes that the lifting is done near Earth's surface, with gravity effectively constant.)ALL Credit goes to Argent at yahoo answers
When we carry an object across a room without lifting it or setting it down we do no physical work on it?
That's correct. For work to be done, the force must have a component in the direction of the movement.
What is The work done holding a 50 kg object at a height of 2 m above the floor for 10 seconds?
The answer is 0. If you used the formula of =>mgh, you would get a value which would be wrong. The question is a trick question. There is no work done in 'holding' an object but work would be done in 'lifting' an object. Hence, 0. ~Dartz
