In physics, work, is defined as the product of force and the amount of displacement in the direction that force is moving. Mathematically it is:
U = F(d)
where,
U = work done on an object
F = force applied to an object
d = displacement of object through the line that the force acts
Work is the product of force and displacement, so it's units are units of force times units of length. Examples could be ft*lb or N*m but the SI unit for the measurement of work is the joule. 1 J is equal to 1 N*m.

What are three elements of mass production?
im not sure... maybe u should READ THE TEXTBOOK! jk i think it was 1) Factories needed better technology 2) Needed a good idea for the product 3) Needed a way to spread the product

How does an inclined plane reduce the forces needed to do work?
by increasing effort distance hence reducing the effort needed to work
What is the relationship between the amount of effort needed to lift the load and the distance of load from the fulcrum?
confusing
When cubed and squared are multiplied how do you get your product?
first you get the denominators the same then you multiply the number you multiplied to the denominator to the numerator then you add the two numerators together and keep the denominators the same then if needed you simplify
Do machines decrease the amount of energy that is needed to do work?
Not usually. They can convert effort into distance and things like that, but the overall energy is about the same.
What is the formula for Effort needed?
If you are thinking of Effort as the FORCE required to move an Object, then the formula is: F = M x A, force = Mass x Acceleration If you are thinking of Effort as the amount of WORK done (in Scientific terms), then the formula is: Work = Force x Distance

they were needed
How does the position of the fulcrum and the location of the load affect the amount of effort force you must exert to lift the load?
To do this you first have to calculate your ideal mechanical advantage (IMA). The IMA is equal to the effort distance (the distance from the fulcrum to where you will apply the effort) divided by the load distance (the distance from the fulcrum to the load). You can then set your IMA equal to your acutal mechanical advatage (AMA) which assumes 100% efficiency. The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your load force is 500 lbs: 5=500/effort force. Therefore the effort force would be 100 pounds.
Relationship between position of fulcrum and effort required to lift load?
A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use. A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use.
As you increase the effort distance what will happen to the force needed?
When you move a fulcrum as close as you can to the effort force and farthest away from the load, you are pushing on the short end of the lever, so it requires the most effort force to push on the lever and lift up the load. When you move the fulcrum farther away from the effort force and closer to the load, you are pushing on the long end of the lever, so it requires less effort force to lift the load.

How do you maintain love?
Reflect upon how you arrived at love in the first place and try to maintain those feelings and that behaviour. This can be achieved even when separated by distance, but extra effort might be needed.
