what is meant by gravity wall

types of reinforced concrete retaining wall and their parts

in case of masonry retaining wall the thickness of wall increases with height because masonry resists the lateral pressure by its weight. thus it is also called gravity retaining wall. the reinforced concrete retaining wall resists the lateral pressure by structural action such as bending and results in thinner section.【Get Price】

what is free fall? a quick lesson in physics

define free fall. in newtonian physics free fall is defined as the motion of an object where gravity is the only force acting upon it. by this definition then a skydiver is never in true free fall even before they deploy their parachute. a skydiver may be pulled towards earth by gravity but they are also affected by air resistance【Get Price】
