Simple machines are basic tools that make work easier by changing the direction or amount of force needed to do a job.

A pulley is a simple machine that is used to change the direction of a force. It consists of a wheel with a groove along its circumference in which a rope or cable can be placed.

A screw is a simple machine that is used to change the direction and amount of force needed to do a job. Its shape creates a wedge-like effect, allowing it to be used to lift, press, turn, or cut materials.

A wheel and axle is a simple machine consisting of two parts: a wheel and an axle. The axle is a rod that runs through the center of the wheel, and the wheel and axle together can be used to transfer force, speed, and direction.

Pulleys, screws, and wheels and axles work by changing the direction or amount of force needed to do a job.

Pulleys reduce the amount of force needed to lift an object by redirecting the force of gravity.

Screws use their wedge-like shape to increase the amount of force needed to be applied to a material
