The formula to calculate displacement is x = ½(v + v0)t. X represents the actual displacement, while V is the velocity. V0 defines the initial velocity, while T represents the time taken.
Know MoreUtilizing this formula for displacement permits an analysis of the difference between the initial and final position of something. The subject of the displacement can be some type of tangible body or a theoretical geometric figure. Displacement is also defined as being the shortest distance from the initial point to a final point. The so-called "displacement vector" represents the length as well as direction of an imaginary path between these two points.

The fluid must go somewhere, however, and so with liquids in containers, this causes their overall height to rise. Gases are also fluids subject to displacement, and they both fill space and are compressible, so an object introduced to a sealed container full of a gas simply decreases the volume of the gas and increases its pressure.
Full Answer >A positive displacement pump works by trapping a specific amount of fluid inside an area of the pump before forcing the fluid to exit the pump through an outlet of some kind. The mechanism that traps the fluid selectively blocks either the entrance or exit when the fluid is moving.
Full Answer >To calculate acceleration, divide the change in velocity by the total time. Acceleration values are expressed in units of velocity per time, including meters per second squared.
Full Answer >Calculate the amount of force exerted on a moving object by using the formula f = m * a. You need to know the mass of the object and its acceleration.
