What are the three kinds of pulley?
The three types of pulleys are fixed pulley, movable pulley, and compound pulley. Fixed pulleys are attached to a stationary object, movable pulleys move along with the load, and compound pulleys combine both fixed and movable pulleys to provide mechanical advantage.
How does a movable pulley move?
A movable pulley is attached to an object being lifted, making it easier to raise the load by reducing the force needed. When one end of the rope is fixed and the other end is pulled, the pulley moves along the rope, resulting in an upward movement of the load.
Explain why the combination pulley is named?
The combination pulley is named because it is composed of both fixed and movable pulleys working together to lift objects. The fixed pulley is attached to a structure while the movable pulley moves with the load, allowing for a mechanical advantage in lifting heavy objects.
What is a fixed and movable pulley used together?
When a fixed and movable pulley are used together, the fixed pulley is attached to a stationary object while the movable pulley is attached to the load being lifted. The combination of these pulleys allows for a mechanical advantage, making it easier to lift heavy objects by requiring less force.
What are fixed and movable pulleys and give examples of each?
A fixed pulley is attached to a support and only changes the direction of the force applied. An example is a flagpole. A movable pulley is attached to the object being moved and reduces the amount of force needed. An example is a crane.

What is the function of a movable pulley?
A movable pulley changes the direction of the applied force, making it easier to lift heavy objects. As the pulley moves with the load, it reduces the amount of force needed to lift the object by distributing the weight between the two sections of the rope.
What is a movable pulley the input force?
A movable pulley can change the direction of the input force. When a force is applied downwards on one end of the rope, it causes the pulley to move upwards, lifting the load attached to the other end of the rope.
What pulley is attached to the load and moves as the load moves Hi I'm Gretchen?
Hi Gretchen, this arrangement to gain mechanical advantage is often referred to as a "block and tackle". It consists of pulleys and ropes, usually not more than four, where the pulley attached to the load moves with the load, and the mechanical advantage is determined by the number of ropes.
What are 2 examples of a pulley?
A fixed pulley, where the pulley is attached to a support and only changes the direction of the force applied. And a movable pulley, where the pulley is attached to the object being moved and reduces the effort required to lift the load.
How are a fixed pulley and a movablepulleydiffrent?
Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.
What is the advantage of a movable pulley?
a fixed pulley changes the direction you are executing the force in. fixed pulleys are made to work with gravity which makes the work you must use less than if you were lifting straight up and against gravity.
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
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.
