Both pulleys and levers are simple machines that help in lifting or moving objects. The main difference is that a pulley is a wheel with a grooved rim around which a rope or chain is pulled to lift objects, while a lever is a rigid bar that pivots on a fulcrum to lift or move objects. However, both pulleys and levers rely on the principle of mechanical advantage to make work easier by reducing the amount of force required to move an object.

there are two kinds of pulleys. A movable pulley and a fixed pulley. But a wheel and axle have a lever and a inclined plane. [someone] :]

Levers and pulleys are both simple machines that can be used to multiply force or change the direction of a force. While levers involve rotating around a fixed point, pulleys use a wheel and axle mechanism to redirect force applied to a rope or cable. Both can be used to make work easier by increasing mechanical advantage.
Levers are simple machines that help to lift or move objects by applying force at a certain point called the fulcrum. Pulleys are also simple machines that consist of a wheel with a groove and a rope or belt wrapped around it, used to lift or pull heavy objects with less effort.
Pulleys are considered part of the lever family because they operate on similar principles of transferring force. Pulleys use a wheel and axle system to redirect and amplify force, just like how levers use a rigid bar to do the same. Both pulleys and levers help make it easier to lift heavy objects by trading off force over distance.
Wrenches are examples of levers. Screwdrivers are a wheel and axle motion. They often use pulleys to move heavy items.
