Difference Between Machine and Mechanism

Published: 4 Jul 2025

Have you ever used a fan, a bicycle, or a washing machine? These things help us do work faster and more easily. Want to know what makes them move? It’s machines and mechanisms. Many people think these two are the same, but they are not. In this article, we will discuss the difference between machine and mechanism in simple words. Let’s learn what each one means and how they are different.

Difference Between Machine & Mechanism

Machine

A machine is a tool that uses energy to do work for us or assist us in performing a specific function or task.
It helps us get the job done with less effort.
It runs using electricity, fuel, or manual force.
It converts energy into useful actions like moving or lifting.
A machine provides results, like spinning a fan or cutting wood.
It includes one or more mechanisms inside to move parts.
It is made of many connected parts some move, some don’t.
It manages the speed, direction, and type of motion needed to do a job.
Machines use straight (linear), round (rotary), or mixed motion.
Machines transform energy into valuable work.
We use machines at home, school, shops, and factories.
e.g Fan, car, washing machine, lathe, mixer, drilling machine.

Mechanism

A mechanism is a part that helps machine parts move in the right way.
It changes or transfers motion from one place to another.
It doesn’t use power by itself it uses the machine’s power.
It only guides or controls the motion it doesn’t do the full job.
A mechanism doesn’t give a final result; it merely facilitates motion.
It’s an internal element of a machine rather than a complete system on its own.
It is only capable of working inside a machine.
Mechanisms commonly use either spinning motion or a back-and-forth movement.
Mechanisms transmit motion or force from one part to another (without changing the energy type).
Used to modify, control or change the speed, timing, or movements of machine parts.
e.g Gears, cams, crank, lever, pulley, slider.

Conclusion

You now know how a machine differs from a mechanism. A mechanism is a smaller part inside the machine that helps move its parts. Machines give us useful outputs like movement or force. Mechanisms only control or guide motion. Both are important and work together in the many tools and devices we use every day.
