A lever is a sturdy bar that is used for lifting heavy objects. The pulley serves the same purpose, but it is a wheel or set of wheels that is operated with a rope or chain. People, along with myself, are able to carry things more easily and quickly because of the contraptions. Thus, saving more of the people's time, money, and effort.

Hydrostatics is the branch of Physics that covers the fluids' aspects when they are at rest. Hydrostatics helped people gain more knowledge about the characteristics of the liquids around them.
The Archimedes screw was supposedly made by the famous scientist, Archimedes. It is used for raising water, getting rid of it from the hold of a larger storage.
Buoyancy is the ability of an entity to float on air or water. It helped us gain the knowledge of how things are able to float on water or air.
The center of gravity is the core of an entity's mass. It helped us know where the point of the whole weight of an object is concentrated. So if that part is supported, the object would remain stable in any stance.
Mechanics is the science that covers the forces and physical energy of objects and their effects. The science has given me a wider perspective of things on how they behave when certain actions are done. Rather, Mechanics has given all of us the knowledge of how things move and what their effects are.
