No you still do the same amount of work

A bicycle incorporates several simple machines, with two key examples being the lever and the wheel and axle. The handlebars serve as a lever, allowing the rider to steer the front wheel, while the wheels themselves function as wheel and axle systems, enabling smooth movement and reducing friction as the bike travels. These simple machines work together to enhance the efficiency and functionality of the bicycle.
When using scissors to cut paper, two simple machines are employed: the lever and the wedge. The scissors act as a lever, where the handles provide a mechanical advantage to amplify the force applied by the user. The sharp edges of the blades function as wedges, allowing them to slice through the paper by concentrating force on a small area.
This really depends on how you define machine; some definitions say that Man is a form of machine - for example, you can describe a man as a heat engine. The key difference is the origins; man is evolved and machines are designed and mechanistic. Because of the evolved nature of man, there is enormous parallelism and complexity and an electro-chemical brain. Although complicated machines are designed, the way these are approached is to either start with a simple machine and add complexity gradually, or to break the system into lots of simple machines. There are some system that are being built using artificial evolution and it may be that one day there is a grey area between machines and animals.
Someone who builds machines is typically called an engineer, specifically a mechanical engineer if they focus on machinery. Additionally, a technician or machinist may also be involved in the construction and assembly of machines. Their roles can vary based on the complexity and purpose of the machines being built.
Tension is the force being used in Simple Machines. As well as simple machines may have a little gravity used, tension is the most used.
simple machines are used by being pulled or pushed

simple machines mean how work is being made easiersimple machines are pulleys levers lifts screws wedges wheels i might of covered all them or there might be one or two more

Levers are useful because they transfer force over a distance. Levers are known for being simple machines and are easy to construct.
Changes the amount of work done by the person and machine.Machines NEVER change the amount of work doneWhat a machine changes is the FORCE required to perform the work, usually by increasing the displacement over which the work is being done. Work equals Force times Distance (W=Fd). Since work doesn't change (remains constant), then displacment must be increased in order to decrease the force (you can see from the work equation that force and displacement are inversely proportional).If you want to lift a 10kg object a height of 1 meter, you will do the same amount of work lifting it straight up with your knees as you would do by using a simple machine such as a ramp. The machine will help you lift the object, but you will at the very least do the same amount of work. See how using a ramp increases the distance the 10kg mass travels to reach the height of 1 meter? Increasing the displacement decreases the required force.An ideal machine will allow you to do the same amount of work. A non-ideal machine will increase the amount of work you do.

If you have 3 quarters, 4 dimes, and 4 pennies, you have $1.19. You also have the largest amount of money in coins without being able to make change for a dollar.
an independent variable will not change with the amount of matter present. Think of it as being independent of the amount of material that is there
If it is a court ordered garnishment (i.e.- child support or similar) you must file a motion with the court to petition for an adjustment in the amount. THis is a fairly simple procedure and anyone can do it for themselves. Check with your local "Clerk of Court" office.
Wrenches are examples of levers. Screwdrivers are a wheel and axle motion. They often use pulleys to move heavy items.
