## What is it called when simple machines work together?

Simple machines are mechanical devices that are used to make work easier. Combinations of two or more simple machines working together are called compound machines.

### What terms are used in simple machine?

They are the simplest mechanisms known that can use leverage (or mechanical advantage) to increase force. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw.

What force is exerted on a machine?

input force
The force exerted on a machine is the input force. The distance the input force acts through is the input distance. The work input equals the input force multiplied by the input distance.

What is a complex machine called?

Complex machines are also called compound machines. Two or more simple machines work together to form a complex machine. Compound machines can do more difficult jobs than simple machines alone.

## Why are computer called a complex machine?

Because the definition of a complex machine is a machine made up of two or more simple machines that make your work easier to do.

### What is a machine in physics?

A machine is essentially a device or tool which allows a force (or effect) applied at one point to overcome a resisting force (or load) at another point. Examples of machines are the lever, pulleys, pliers, wheel barrows, nut crackers, the inclined plane, the wedge, wheel and axle, screw jack and so on.

How does a pulley work?

Pulleys are simple machines consisting of a rope and an oval wheel. The ropes fit into the groove in the wheel, & the wheel spins by pulling the rope. Pulleys are commonly used to lift objects, especially heavy objects. With a two-wheel pulley, you reduce the force used to lift the same load.

What is the work output of a machine?

In physics, work output is the work done by a simple machine, compound machine, or any type of engine model. In common terms, it is the energy output, which for simple machines is always less than the energy input, even though the forces may be drastically different.

## How is the work output of a machine related to its work input?

Solution: Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine. For an ideal machine, the work output is equal to the work input i.e the efficiency is 1.

### What does the machine do to the object to increase output distance?

The machine does to the object to increase the output distance. In a machine or mechanical device, there is a concept of work done by the human on the machine (input) and work done by the machine (output).

What are 3 examples of machines?

MACHINE 3 examples of machines wheelchairs chopsticks and scissors what common machine is a screwdriver that is used to pry off the lid on a paint can? lever the work you do on a machine is called? work input the work done by a machine on an object is called? work output

How is work done on an object?

In physics we say that work is done on an object when you transfer energy to that object. If one object transfers (gives) energy to a second object, then the first object does work on the second object. Work is the application of a force over a distance.

## What is mechanical work in simple words?

The simplest case of mechanical work is when an object is standing still and we force it to move. The energy of a moving object is called kinetic energy. For an object of mass m, moving with velocity of magnitude v, this energy can be calculated from the formula E= 1/2 mv^2. There are two types of energy in many forms:
