Because there is a force of gravity constantly pulling it towards the center of earth. When you exert enough force to over come the gravity acting on an object it is lifted
A pulley system can change the direction of a force, making it easier to lift or move heavy objects. By distributing the force over multiple ropes and pulleys, it can also reduce the amount of force required to lift an object. This allows for more efficient use of energy in lifting objects.
Some everyday objects that are levers include scissors, crowbars, and tongs. These objects use a pivoting point, or fulcrum, to help lift or move things with less force.
Tools like cranes, forklifts, hoists, and jacks are commonly used to lift heavy objects. They work by using mechanical force or hydraulic power to raise and move objects safely and efficiently.
A wedge is a simple machine that is used to split, lift, or separate objects by applying a concentrated force. It converts the force applied to it into a larger force perpendicular to its length, making it easier to break or lift apart objects.
A lever reduces the effort needed to lift objects by allowing the force to be applied farther away from the pivot point, increasing the lever arm. This leverage multiplies the force applied, making it easier to lift the object.
Pulleys reduce the force required to lift heavy objects.

Tornadoes are more likely to lift lighter objects as they generate an upward force with their strong winds. Heavier objects may be more difficult for tornadoes to lift unless they are caught in the vortex of the tornado's winds.
The force that pushes things up is called lift. It is the force that acts perpendicular to the direction of the flow of a fluid (such as air or water) and helps objects to rise or stay airborne. This force is commonly associated with flying objects like airplanes and birds.
Force lift refers to using the power of the Force to levitate and manipulate objects without physical contact. It is a common ability demonstrated by Force-sensitive individuals in the Star Wars universe, allowing them to move objects with their minds.
Using tools such as levers, pulleys, or hydraulic systems can help people lift heavy objects with less force by multiplying the input force exerted. These mechanisms allow for a distribution of the load over a larger area, making it easier for individuals to lift heavy objects.
Example to lift a force upward we use 2 pulleys. Then the force becomes half of the force we will have to use with one pulley.HOW?"
There are a variety of different designs for pulleys, depending upon what you need to do with them. A pulley can be used to change the direction of a force without changing the amount of force that you apply, but there are also pulleys that do reduce the amount of force you have to use to lift something.
