Yes, if an outside force is provided.
Yes, since motion is only relative.
No, since a system which is not moving has no energy.
No, because of the way work is defined.

No work was done.
Yes, since a force acts and the object moves, and work is force times distance.
Yes, since it takes energy to turn an object.
No, because the object has constant speed.
No, because the force and the displacement of the object are perpendicular.

It is impossible to tell from the information given.
It remains constant.
It increases continually.
It decreases continually.

The kinetic energy of the object.
The gravitational potential energy of the object.
The work done on the object by the force.
The power supplied to the object by the force.
The kinetic energy of the object.
The elastic potential energy of the object.
The work done on the object by the force.
The power supplied to the object by the force.
Yes, as long as the total energy is positive.
Yes, since the choice of the zero of potential energy is arbitrary.
No, because the kinetic energy of a system must equal its potential energy.
No, because this would have no physical meaning.
