Is dropping a ball doing work?
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.
How can the concept of work be negative in the context of physics?
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.
Is pushing up against a wall doing work?
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.
What is the unit for work in physics?
The unit for work in physics is the joule (J).
What is the formula for calculating total work in physics?
The formula for calculating total work in physics is: Work Force x Distance.
Where can you work as a physics engineer if you are not an MIT graduate etc?
If you are not a Graduate Engineer you should be doing the work

What is the rate of doing work of using energy?
(physics) the rate of doing work; measured in watts (= joules/second) - See more at: http://www.chacha.com/question/what-is-the-rate-of-doing-work-or-using-energy-(58%26%2345%3B19)#sthash.l6xRuIk4.dpuf

Is letting a pencil fall to the ground work?
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.
Is the lady doing any work if she take the lift from the ground floor to the fifth floor holding a bag in her hand?
In physics, work is defined as the transfer of energy that occurs when an object is moved over a distance by an external force. In this case, while the lady is using the lift, she is not doing any mechanical work herself, as the lift is doing the work to move her and the bag to the fifth floor. However, she is exerting some force to hold the bag while being lifted, but this is minimal compared to the work done by the lift. Thus, in a strict physics sense, she is not doing work in the way that the term is typically defined.
What does the scientific word work mean?
in physics, it means the product of a force times a distance, which is an energy.
What is the unit for work in physics?
The unit for work in physics is the joule (J).
What does being excellent at math have to do with doing well in physics and chemistry?
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.
What does it mean to be diligent at work?
Being diligent is a serious attitude toward the work you are doing.
