A pulley helps lift an object by reducing the amount of force needed to lift it. When a rope is threaded through a pulley, it allows you to pull down on one end of the rope while the object is lifted up on the other end, distributing the weight between multiple ropes and making it easier to lift the object.

What force is required to lift something on a pulley?
The force required to lift an object using a pulley system depends on the weight of the object being lifted. The force needed is equal to the weight of the object being lifted plus the force required to overcome any friction in the pulley system. The mechanical advantage provided by the pulley system can help reduce the amount of force needed to lift the object.
What is the relationship between the weight of an object and the pulley tension required to lift it?
The weight of an object is directly proportional to the pulley tension required to lift it. This means that as the weight of the object increases, the tension in the pulley system needed to lift it also increases.
Is a combined pulley easier to lift any other pulley?
A combined pulley system makes it easier to lift an object compared to a single pulley system. By distributing the load across multiple pulleys, the force required to lift the object is reduced.
What is when the pulley moves with the object?
When the pulley moves with the object, it is known as a moving pulley system. In this setup, the pulley acts as a wheel that is also being pulled along with the load, which can help to reduce friction and make it easier to lift the object. This configuration is often used in various mechanical systems to help distribute weight and facilitate movement.
What is a simple machine that changes the direction of force to lift an object?
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.

Do the moveable pulley decreases the input force?
Do the moveable pulley decreases the input force?
What kind of pulley can increase the effort force?
A movable pulley can increase the effort force. By attaching the pulley to the object being lifted and pulling downward, the force required to lift the object is reduced, making it easier to lift heavier loads.
Does the force used to lift an object using a single pulley alter depending on the size of the pulley?
no
What is one advantage of using a pulley system?
One advantage of using a pulley system is that it can help to reduce the amount of force needed to lift a heavy object. By distributing the load across multiple ropes and pulleys, the effort required to lift the object is decreased.
What lifts up object faster a big pulley or a small pulley?
A big pulley generally lifts an object faster than a small pulley. This is because a big pulley has a larger diameter, which means the object will be lifted a greater distance in each rotation compared to a smaller pulley.
How does a moveable pulley change the input force?
A moveable pulley reduces the amount of input force needed to lift an object. By attaching the pulley to the object being lifted, the force needed to move the object is distributed between the pulling force and the weight of the object itself, making it easier to lift.
What does a movable pulley change?
A movable pulley changes the direction of the force applied to move an object. It allows the user to pull downwards or sideways instead of having to lift the object straight up. This type of pulley also reduces the amount of force needed to lift the object.
