A pulley is a simple machine that changes the direction of force. It consists of a grooved wheel and a rope or cable that runs along the groove, allowing you to pull downwards to lift an object upwards.
A simple machine changes the direction of effort by altering the direction in which force is applied. For example, a pulley system or a lever can redirect the force applied by a person in one direction to produce movement or work in another direction. This change in direction allows the machine to make tasks easier or more efficient to perform.
A pulley is a simple machine that changes the direction of force to lift an object. By looping a rope over a pulley, you can pull down to lift the object up.
A pulley is a simple machine that changes the direction of the force needed to move an object without changing the amount of force required. By using a pulley, you can apply a downward force to lift an object upwards.
A machine that changes the direction or amount of force needed to do work is known as a "simple machine." Simple machines include tools like levers, pulleys, and gears that help make work easier by either amplifying or redirecting forces.
A pulley is a simple machine that changes the direction over which force is exerted. It consists of a wheel with a groove that a rope or belt can sit in, allowing the user to pull downward to lift an object upward.

A pulley is a simple machine that changes the direction of the force required to perform a task without changing the amount of force needed. By redirecting the force, pulleys make it easier to lift or move heavy objects.
A machine that changes the direction or amount of force needed to do work is called a simple machine, which includes tools like levers, pulleys, and ramps. Simple machines allow us to make tasks easier by redistributing the force we apply over a larger distance or in a different direction.
Simple
Levers, inclined planes, and compound pulleys all do that.
A straw is not a simple machine. Simple machines are mechanical devices that change the direction of a force. A straw does not redirect the direction of the force.
A type of machine that changes the direction or amount of force needed to do work is called a simple machine. Examples include levers, pulleys, and gears. These machines help make tasks easier by altering the force needed to accomplish them.
A lever is a simple machine that changes the direction or magnitude of the force applied to it. It can be used to increase the motion or force output from the input work.
