Why is it easier to pull down on a rope over a pulley than to pull down on a rope thrown over a wood beam?
A pulley is a wheel and axel which reduces the friction created by a cable being pulled across it, a rope over a wood beam would have increased friction, making it more difficult to pull.
Numerous pulleys would reduce the amount of tension force required to move a load, making it easier to pull.

What is an example of a movable pulley?
An example of a movable pulley is a flagpole. When you pull down on one end of the rope, the pulley at the top of the flagpole moves with the flag, making it easier to raise and lower the flag.
What would a fixed pulley be used for?
A fixed pulley is typically used to change the direction of an applied force. It can make it easier to lift heavy objects by allowing you to pull down on the rope instead of lifting the object directly.
What is 1 moveable pulley attached to a load?
A single moveable pulley attached to a load reduces the amount of force needed to lift the load by half. The pulley is free to move up and down, allowing for easier lifting and lowering of the load.
How does a fixed pulley make work easier?
A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.
How does a pulley make it easier to lift something?
A pulley reduces the amount of force needed to lift something by distributing the load across multiple ropes or cables. This allows you to pull down on the rope with less effort, making it easier to lift a heavy object.

How is a lever pulling down then pulley pulling up?
When a lever pulls down, it exerts a downward force on one end of the pulley system. The pulley system redirects this downward force into an upward force on the other end, allowing for lifting or moving objects vertically. This mechanical advantage of the pulley system makes it easier to lift heavy loads with less effort.
Which pulley system can make work easier?
A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.
What is a hanging curveball?
A hanging curveball is a curveball that is thrown in a way that makes it easier to hit. A good example of one is a slow curveball that is thrown down the middle. If you get one of these babies thrown to you while your at the plate, swing at it. It is an easy pitch to crush for a dinger or at least a double.
What machine allows you to lift things by pulling down on a rope?
A pulley system allows you to lift things by pulling down on a rope. By looping the rope through a pulley wheel, you can change the direction of the force needed to lift the object, making it easier to lift heavy loads. The more pulleys you add to the system, the more the mechanical advantage and the easier it becomes to lift the object.
Pulling down on a rope to hoist a sailboat is an example of a machine?
It is a type of machine that is changing the direction over which a force is exerted.
How is a fixed pulley useful?
A fixed pulley changes the direction of a force, making it easier to lift objects vertically by allowing you to pull down instead of up. It does not provide any mechanical advantage in terms of reducing the amount of force needed to lift the load.
What is a fixed single pulley that is used to lift a block?
It makes the block easier to lift by changing the direction of the force needed to lift it.
