What is the 3 Types of pulley?
The three main types of pulleys are fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are stationary and only change the direction of the force, while movable pulleys are attached to the object being moved and reduce the effort needed. Compound pulleys combine both fixed and movable pulleys to provide a mechanical advantage for lifting heavy loads.
How does a pulley change the input force?
A single pulley only changes the direction of the applied force. A second or more pulleys on the same rope will multiply the force applied by decreasing the distance of the applied force. This arrangement is called a block and tackle. Two pulleys double the force and halve the distance the force acts upon the mass. Three will triple the force while reducing the distance by 1/3, and so on. If 1 pound of force is applied to a rope with four pulleys on it over the distance of 10 feet of rope it will raise a 4 pound weight 2 1/2 feet.
Why do pulleys mean that less force is required to lift the object?
Of course less force as effort to lift heavy force as load. Hence mechanical advantage. But as far as energy is concerned it could neither be created nor destroyed. So with less effort we have to move to a longer distance with the load moved only for a small distance. So small force x longer distance = large force x small distance = constant
What type of pully can multiply effort force?
Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
What can lift things or at least try but only while filled or empty it lies?
Glove
Will having to lift heavy things make your belly button piercing mess up?
Only if you snag the bar with the heavy object and tear it.
Why do ski lifts have pulleys?
A ski lift is operated by a pulley; they need them to operate the lift; without them, there would only be a cable and chair lift floating in mid- air

Should you lift heavy weights when triaining to play baseball?
The only way to add muscle is to lift heavy weights. Your muscles need to be overloaded to break them down and force them to adapt. You may be sore, but heavy weights is a necessity.
How does a tornado suck up all things?
No. Extremely heavy objects are unlikely to be lifted in even the most violent tornadoes. Most tornadoes are not particularly destructive, and only lift relatively light objects.

a pulley system uses a 250-N force to lift a 2,740-N crate, What is the mechanical advantage of the system?
Answer: Mechanical advantage can be achieved just by adding more loops or pulleys. It is given that to lift a crate, a pulley system exerts a force of 2,740 newtons. It is required to find the mechanical advantage of the pulley system if the input force is 250 newtons What is the mechanical advantage of the pulley system if the exerted force changes from 2,740 newtons to 250 newtons? As if the force does some work, it increases the distance. Mechanical advantage does nothing with the number of pulleys. It only depends on the weight that is to be lift. Also, F1/F2 = 2740/250 = 10.96 The multiple pulleys create mechanical advantage. It can be achieved just by adding more loops or pulleys. Therefore, Mechanical advantage can be achieved just by adding more loops or pulleys.

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.
Why is it easier to lift heavy objects on the moon than on earth?
It is easier to lift heavy objects on the Moon than on Earth because the Moon's gravitational pull is only about one-sixth that of Earth's. This reduced gravity means that objects weigh significantly less on the Moon, making them easier to lift and move. Consequently, the same force exerted to lift an object results in a greater acceleration on the Moon compared to Earth.
