How does a movable pulley reduce the input force needed to lift a weights?
a lever
What is a Disadvantage of a fixed pulley?
The pulley does not reduce the force needed for lifting an object. Also, the pulley can't readily move to another location, but that may be an advantage depending on the application.
Does a pulley use less force?
There are a variety of different designs for pulleys, depending upon what you need to do with them. A pulley can be used to change the direction of a force without changing the amount of force that you apply, but there are also pulleys that do reduce the amount of force you have to use to lift something.
How does the pulley make work easier?
You don"t have to pull the full weight. They reduce the force needed to move an object.
Why is a pulley a force multiplier?
Why are pulley force multipliers? Pulley are force multipliers because they expand the distance over which it operates.

What tasks did the ancient use the pulley for?
Pulleys reduce the force required to lift heavy objects.

What is the purpose of a inclined plane with a pulley?
To reduce the amount of force needed to carry objects into the truck k12
What jobs did the pulley do?
A pulley is a wheel with a groove on its edge for holding a rope or cable. pulleys are usally used in sets desinged to reduce the amount or force needed to lift a load.

What does a pulley cause?
When used appropriately, a pulley can be used to reduce the amount of force needed to move an object. By using multiple pulleys, one can change the direction that force needs to be applied to move an object, as well as reducing the amount of force that is necessary through mechanical advantage.
How does the force applied to a pulley affect its motion?
force applied to a pulley
What does a pulley do with force?
A pulley directs the force in a rope into a new direction.
How did the pulley affect the amount of force needed?
A pulley is a force multiplier. (it swaps force for distance).
