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.
The length from the fulcrum to the load is known as the load arm or effort arm. It is the distance between the fulcrum and the point where the force is applied to lift the load. This length affects the amount of force needed to lift the load.

cell works as an open system i.e it takes in substances needed for metabolic activity through its cell membrane.Then it performs its metabolic processes assigned to it .Product and by-product are form in metabolism.Cell either utilizes the product or transport them to other cells.The by-product either stored out of the cell.
To calculate distance with velocity and weight, you can use the equation for work: Work = Force x Distance. The force can be calculated by multiplying the weight with gravity. Velocity can then be used to determine the time it takes for the object to travel that distance using the equation Distance = Velocity x Time.
The amount of effort needed to lift a load decreases as the distance of the load from the fulcrum increases. This is because a longer distance from the fulcrum provides a mechanical advantage, making it easier to lift the load.
The trade-off between effort force and effort distance refers to the relationship where increasing the distance over which a force is applied (effort distance) can reduce the amount of force (effort force) needed to accomplish a task. This trade-off occurs in simple machines such as levers, where adjusting the distance from the pivot point affects the amount of force required to move an object. A longer effort distance allows for less force to be exerted, while a shorter distance requires more force.
The location of the fulcrum and load affects the amount of effort needed to lift the load and the distance the load can be moved. Placing the fulcrum closer to the load reduces the effort needed but limits how far the load can be moved, while placing the fulcrum closer to the effort increases the distance the load can be moved but requires more effort.
Increasing the distance from the fulcrum to the load will increase the effort needed to lift the load. This is because when the load is farther from the fulcrum, a greater force is required to overcome the increased resistance due to the longer lever arm. Conversely, decreasing the distance from the fulcrum to the load will require less effort to lift the load.
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
An inclined plane reduces the force needed to do work by increasing the distance over which the force is applied. By spreading the work over a longer distance, the force required is reduced. This makes it easier to lift or move objects along the inclined plane compared to lifting them vertically.
The amount of effort required to lift a load is inversely proportional to the distance the load is from the fulcrum. This means that the closer the load is to the fulcrum, the more effort is needed to lift it, and vice versa when the load is farther from the fulcrum.
You could halve the effort required by moving the load closer to the fulcrum. Placing the load 0.5 meters from the fulcrum would reduce the effort needed to lift it. This is based on the principle of a lever, where the effort needed is inversely proportional to the distance of the load from the fulcrum.
how does moving a fulcrum on a lever change the amount of force needed to move an object
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.
A wedge is an inclined plane that reduces the effort force needed to split or lift objects. It works by increasing the distance over which the force is applied, allowing the force to do more work with less effort.
The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no effect on the quantity of work.
