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 fixed pulley mean?
A fixed pulley is a type of pulley that is attached to a stationary object. It changes the direction of the force applied to move an object, but does not provide any mechanical advantage in terms of reducing 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.
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 a simple machine that changes the direction of force needed to move an object but not the amount of force needed?
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.

Why is a pulley a force multiplier?
A pulley is a force multiplier because it allows a person to lift a heavy object with less force than would be needed without the pulley. By redirecting the force needed to lift the object, a pulley system can increase the efficiency of the process and reduce the amount of force required.
In a movable pulley system where does the other effort come from?
In a movable pulley system, the other effort comes from the weight of the object being lifted. The movable pulley reduces the amount of force needed to lift the object by distributing the load between the pulling force and the weight of the object. As a result, the effort needed to lift the object is divided between the pulling force and the weight of the object itself.
What type of work is done by a movable pulley?
A movable pulley reduces the force needed to lift an object by changing the direction of the force required. This type of pulley is attached to the object being lifted and moves with it, allowing for easier lifting.
What is the difference between a fixed pulley and movable pulley?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
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.
What is a double pulley system?
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.
What is the relationship between the effort and the weight of an object being lifted over a simple pulley?
the effort needed to lift an object is about the same as the weight of an object:)
