ACCELERATION: begin to move more quickly
- increase in rate, amount or extent
-undergo a change in velocity
AXLE: a supporting shaft or member on or with which a wheel or a set of wheels revolves.
BEARING: interface between the axle and the chassis.
BUSHING: smooth sleeve placed in the hole that gives axle a smoother rubbing surface, which means less surface friction.
CENTER OF MASS: a point representing the mean position of the matter in a body or system.
CHASSIS: a mechanical component that must provide structural support for the motor, wheels, axles, e.t.c...
DISTRIBUTION OF WEIGHT: is the apportioning of weight within a vehicle
ENERGY: having the ability to do work.
FORCE: physical strength or energy as an attribute of action or movement.
FRICTION: the resistance that one surface or object encounters when moving over another.
■ the action of one surface or object rubbing against another
FLUID FRICTION: air resistance.
INERTIA: resistance to change in some other physical property. (fancy word for "resitance to change")
KINETIC ENERGY: energy of motion or the energy a moving object has.
LUBRICANTS: a substance that reduces friction.
MASS: numerical measurement of inertia.
MOMENTUM: the impetus gained by a moving object.
MECHANICAL ADVANTAGE: the ratio of the output force produced by a machine to the applied input force.
POTENTIAL ENERGY: the energy that is stored and held in readiness.
POWER OUTPUT: amount of power a component, circuit or system can deliver to a load.
ROTATIONAL INERTIA: the property of an object to resist changes and its rotational state of motion.
SPEED: distance traveled divided by the time of travel.
SURFACE FRICTION: mutual contact of irregularities between the touching surfaces.
THRUST BEARING: a bearing which sustains axial loads and prevents axial movement of a loaded shaft.
THRUST WASHERS: eliminate the rubbing friction of a wheel touching the frame.
TORQUE: a force that tends to turn or rotate things.
TRACTION: the act of being pulled.
TRANSMISSION: any device that transmits mechanical energy from one place to another.
VELOCITY: rapidity or speed of motion.
WEIGHT: a product of the amount of mass an object has and the amount of gravity pulling on the mass.
