Of course less force as effort to lift heavy force as load. Hence mechanical advantage. But as far as energy is concerned it could neither be created nor destroyed. So with less effort we have to move to a longer distance with the load moved only for a small distance.
So small force x longer distance = large force x small distance = constant

How do pulley systems work?
Pulley systems work by distributing the weight of an object across multiple ropes and pulleys, making it easier to lift heavy loads. The more pulleys in the system, the less force is required to lift the object. As you pull down on one end of the rope, the weight is distributed evenly across the pulleys, reducing the effort needed to lift the object.
How does gravity help pulleys?
Gravity helps pulleys by providing the force needed to move the object being lifted. As the object is pulled down by gravity, the pulley system redirects the force, making it easier to lift the object by changing the direction of the force needed. This allows for heavier objects to be lifted with less effort.

What has pulleys in it?
A typical example of a device that contains pulleys is a crane. Cranes use multiple pulleys to lift and move heavy loads with less force required from the operator.
How could a pulley multiply the distance but not the force of the effort?
A pulley system can multiply distance but not force of the effort because the force applied is spread out over a greater distance as the rope is fed through the pulleys. This enables the user to move an object a longer distance with less force, as the trade-off is a decrease in the force required for each unit of distance traveled.
Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.

How does a pulley hoist system work to lift heavy objects?
A pulley hoist system works by using multiple pulleys to distribute the weight of a heavy object, making it easier to lift. As you pull on the rope attached to the pulleys, the force is spread out across the pulleys, reducing the amount of force needed to lift the object. This mechanical advantage allows you to lift heavier objects with less effort.
What has pulleys in it?
A typical example of a device that contains pulleys is a crane. Cranes use multiple pulleys to lift and move heavy loads with less force required from the operator.
Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
How could a pulley multiply the distance but not the force of the effort?
A pulley system can multiply distance but not force of the effort because the force applied is spread out over a greater distance as the rope is fed through the pulleys. This enables the user to move an object a longer distance with less force, as the trade-off is a decrease in the force required for each unit of distance traveled.
Do you need more or less Force for a heavy object?
You generally need more force to move a heavier object due to its greater mass. More force is required to overcome the object's inertia and accelerate it.
What are positive aspects of pulleys?
Pulleys allow for the redirection of force, making it easier to lift heavy objects by distributing the load across multiple ropes and pulleys. They also provide mechanical advantage, requiring less effort to lift an object compared to lifting it directly. Additionally, pulleys can be used to change the direction of the force applied, making them versatile tools in various applications.
Do you have to exert more force than the graveity to lift something?
Yes. Only slightly less, depending on the required acceleration.Yes. Only slightly less, depending on the required acceleration.Yes. Only slightly less, depending on the required acceleration.Yes. Only slightly less, depending on the required acceleration.
How do compound pulleys work?
Compound pulleys work by combining fixed and movable pulleys in a single system to provide a mechanical advantage. The fixed pulleys are attached to a stationary object, while the movable pulleys are attached to the load being lifted. As the rope is pulled, the load is lifted by distributing the weight across multiple pulleys, making it easier to lift heavier objects with less force.
