In physics, work is defined as the transfer of energy to an object by applying a force through a distance. When dropping a ball, gravity is the force acting on the ball, but no energy is transferred by an external force so technically dropping a ball is not considered as doing work in the physics sense.
In physics, work is considered negative when the force applied to an object is in the opposite direction of the object's displacement. This means that the force is doing work against the motion of the object, resulting in a negative value for the work done.
Physically pushing against a wall can be considered as doing work in a physics context, as work is defined as the force applied over a distance. The force you exert on the wall does not result in any displacement of the wall, but work is still being done in the physics sense, as long as the force is being applied.
The unit for work in physics is the joule (J).
The formula for calculating total work in physics is: Work Force x Distance.

No, letting a pencil fall to the ground does not involve doing any work in the physics sense. Work is defined as force multiplied by distance over which the force is applied. When a pencil falls, gravity does the work, not the person letting it fall.
in physics, it means the product of a force times a distance, which is an energy.
Physics and chemistry use mathematics in order to quantify their observations about the world. Most mathematics were invented by scientists who needed the math to quantify their work.
Being diligent is a serious attitude toward the work you are doing.
Power is the rate of doing work
