Pendulum clock: The swinging motion of the pendulum relies on gravity to maintain a consistent rhythm. Waterwheel: Gravity pulls the water downward, causing it to turn the wheel and generate mechanical energy. Roller coaster: Gravity propels the cars along the track, as the potential energy at the highest point is converted into kinetic energy due to gravity pulling the cars downward.
A Machine is something that helps do work. Work, in mechanics, is the amount of energy output over a distance. A force is what does the work, so a force acting over a distance does work...which is what machines help do. Further, the amount of time that a force takes to do work will determine the POWER output.
Gravity needs no specific "devices". ANY mass in the Universe attracts ANY other mass. So, the only thing you need for gravity to work, is to have two objects that have mass - so basically, any two objects.
The work done in lifting an object is positive, as energy is input to move it against gravity. The work done in lowering an object is negative, as the object is moving in the direction of the force of gravity, and energy is being released. Overall, the work done will depend on the distance the object is lifted or lowered and the force applied.
Some common questions about simple machines include: How do simple machines make work easier? What are the different types of simple machines? How do simple machines affect force and distance in work? How can simple machines be combined to create complex machines?

how is machines related to work
Do you mean "change"? If you're talking about "simple machines", the usual answers are direction (eg., with a pully), speed, and force.
Yes, peristalsis will work against gravity.
Machines are designed to make work faster and easier. These machines do so by taking some of the manual work off of you.
n
are machines used to simplify work in the office.
Machines were invented to make work easier.
