"Work" is the product of force times distance; so if you apply a force without moving, or if you have a movement without a force, then there is no work involved.

What cannot be done by a simple machine?
Increase Work
What happens to internal energy when mechanical work is done?
Increase.
How do you calculate the work done on a object?
To calculate work done on an object one needs to use the following equation; work = force x distance or W = F x d
How much work must be done on a 5kg snowborad to increase its speed from 2ms to 4ms?
1500 j
Why isn't work done as you hold a book motionless over your head?
Because it does not require movement or apply force toward the body therefore, this is not work. :)

What are the two ways in which you can increase the amount of work done?
By increasing the distance also increasing the amount of work done
What is the increase in work done by a lever called?
Mechanical advantage .
What happens to internal energy when mechanical work is done?
Increase.
If work is don adiabatically on a system will the internal energy increase or decrease?
If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.
What the realationsip between work and mechanical energy?
I think it helps to think - informally - of work as the "transfer of energy". Work is said to be done when you apply a force along a certain distance; and energy is required to do this work. The work done on the system may increase the system's potential energy, or - if done against a force of friction - it may increase its heat energy.
When mechanical work is done on a system there is an increase in what?
both temperature and internal energy
What is added to an object when work is done on it?
In that case, the object's energy should increase.
How much work must be done on a 10kg bicycle to increase its speed from 2 M's to 3 M's?
Work done = increase in kinetic energy ie 1/2 * 10 * (3+2)(3-2) [recall a2 - b2 = (a+b)(a-b)] Hence work done = 25 joule.
Do you work as a team or single work as an engineer?
You do both. Some tasks require working in a team but others are done alone.
How does technology help to increase productivity?
technology is all about innovations to get the work done in simpler and faster way.so as the work goes on being completed faster the productivity will itself increase.
How do you calculate the work done on a object?
To calculate work done on an object one needs to use the following equation; work = force x distance or W = F x d
