# Weight distribution

Weight distribution is the apportioning of weight within a vehicle, especially cars, airplanes, and trains. [1]

## Acceleration

In physics, acceleration is the rate of change of velocity of an object with respect to time.

## Airline

An airline is a company that provides air transport services for traveling passengers and freight.

## Airplane

An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller or rocket engine.

## Automobile handling

Automobile handling and vehicle handling are descriptions of the way a wheeled vehicle responds and reacts to the inputs of a driver, as well as how it moves along a track or road.

## Car

A car (or automobile) is a wheeled motor vehicle used for transportation.

## Center of gravity of an aircraft

The center of gravity (CG) of an aircraft is the point over which the aircraft would balance.

## Center of mass

In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating.

## Center of percussion

The Center of Percussion is the point on an extended massive object attached to a pivot where a perpendicular impact will produce no reactive shock at the pivot.

## Drag racing

For the drag queen reality competition program, see RuPaul's Drag Race. Drag racing is a type of motor racing in which automobiles or motorcycles (usually specially prepared for the purpose) compete, usually two at a time, to be first to cross a set finish line.

## Free surface effect

The free surface effect is a mechanism which can cause a watercraft to become unstable and capsize.

## Mass distribution

In physics and mechanics, mass distribution is the spatial distribution of mass within a solid body.

## Roll center

The roll center of a vehicle is the notional point at which the cornering forces in the suspension are reacted to the vehicle body.

## Tilt test (vehicle safety test)

The tilt test is a type of safety test that certain government vehicle certification bodies require new vehicle designs to pass before being allowed on the road or rail track.

## Traction (engineering)

Traction, or tractive force, is the force used to generate motion between a body and a tangential surface, through the use of dry friction, though the use of shear force of the surface is also commonly used.

## Train

A train is a form of transport consisting of a series of connected vehicles that generally runs along a rail track to transport cargo or passengers.

## Trucking industry in the United States

The trucking industry serves the American economy by transporting large quantities of raw materials, works in process, and finished goods over land—typically from manufacturing plants to retail distribution centers.

## Vehicle

A vehicle (from vehiculum) is a machine that transports people or cargo.

## Weight

In science and engineering, the weight of an object is related to the amount of force acting on the object, either due to gravity or to a reaction force that holds it in place.

## Weight transfer

Weight transfer and load transfer are two expressions used somewhat confusingly to describe two distinct effects: the change in load borne by different wheels of even perfectly rigid vehicles during acceleration, and the change in center of mass (CoM) location relative to the wheels because of suspension compliance or cargo shifting or sloshing.
