Pulleys with belt
They consist of two pulleys or wheels that are a certain distance apart. Their axles are parallel and they rotate simultaneously due to the effect of the belt
Pulley trains with belts
It's a system of pulleys, or wheels, with a belt
formed by more than two wheels.
Friction drives
Friction drives are made up of two or more wheels that are in contact, The ratio between the rotation velocity of the wheels or pulleys depends on the relative size of the wheels.
Gear train
The gear ratio between the drive wheel and the dnven wheel dependson the number ol geared teeth m the system:

linear motion mechanisms
Movable pulley
A moveable pulley is a set of two pulleys, one is fixed while the other can move in a linear direction
Compound pulley
This is a system of fixed and moveable pulleys, often called block and tackle.
Fixed pulley
A fixed pulley is a wheel that has a groove around lt into which a rope,cham or belt fits

Around us we can see many moving obiects and mechanisms that produce movement that we can also call motion.
