A pulley is a simple machine that uses a wheel and rope to lift heavy objects. As you pull the rope, the pulley helps reduce the amount of force needed to lift the object by distributing the weight across multiple strands of rope. This makes it easier to raise heavy loads by allowing you to exert less effort.

What uses a rope and a wheel to move an object?
A pulley system uses a rope and a wheel to move an object by reducing the amount of force needed to lift the object. The rope is threaded through the wheel, allowing the user to pull down on one end of the rope to lift the object on the other end. This simple machine is commonly used in construction, transportation, and lifting heavy objects.
A pulley can be thought of as an inclined plane wrapped around a cylinder?
Yes, a pulley is a simple machine that uses a wheel and axle to redirect the force applied to it. By wrapping a rope around the wheel, the pulley can change the direction of force needed to lift an object. This change in direction allows for easier lifting of heavy loads.
What simple machine uses a wheel with a rod or rods through its center that will help it lift or move a load?
A pulley system uses a wheel with a rod through its center to lift or move a load. The pulley reduces the amount of force needed to lift heavy objects by distributing the weight across multiple ropes or chains.
What does pulley do?
A pulley is a simple machine that uses a wheel and axle to lift or move objects by changing the direction of the force applied. It allows you to easily lift heavy objects by distributing the weight across multiple ropes or chains. Pulleys are commonly used in various systems, such as construction, elevators, and exercise equipment.
Is a crowbar a pulley or a lever?
A crowbar is a lever because it has a fixed fulcrum (the pivot point) that allows it to lift or move heavy objects by applying force at one end. It is not considered a pulley, which uses a wheel and rope to lift objects by changing the direction of the force applied.

What is one disadvantage of using pulleys?
A pulley uses leverage to displace the pressure of an object, making said object easier to lift

Could a small person lift a heavy person?
Yes, if a small person uses a machine, like a lever or a pulley, to lift a person of more mass than the smaller person.
What simple machine uses grooved wheels and a rope belt or chain?
A pulley is a simple machine that has a grooved wheel that holds a rope or a cable. This is used to lift heavy loads. It is also known as sheave or drum.
What does pulley do?

What does a pulley and lever stand for?
A pulley is a simple machine that uses a wheel and rope to lift or lower objects. A lever is a simple machine that uses a rigid bar resting on a pivot to help move objects with less force. Both pulleys and levers are tools that make it easier to lift heavy objects or move loads.
What machine uses a pulley?
A block and tackle. an ellevator, a winch,
Is a Pulley a moving inclined plane?
No. A pulley is a simple machine in its own right.
How does a movable pulley make work easier?
A movable pulley reduces the force needed to lift an object by allowing the load to be shared between two segments of the rope. As you pull down on one end of the rope, the object is lifted by the pulley system. This setup effectively halves the amount of force needed to lift the object.
