| Question | Answer |
|---|---|
| coast | to move without being continunsly pushed or pulled |
| bearings | strutures that help parts move freely |
| normal force | the force that comes from the struture on which on object is located |
| net force | the overall force acting on an object,when all the indivual forces acting on the object adding together |
| velocity | an object's speed and direction |
| lubrication | a substance (such as oil or grease) put between two surfaces to reduce friction |
| friction | a force that opposes motion |
| iteration | a repitition that attempts to improve on a process or product |
| reference point | an object or location with which the position of a second object detrimine if the second object is moving |
| force | a push or pull |
| chassis | the frame and wheels of an vehicle |
| veer | a change direction or course |
| motion | a change in the position of an object over time |
| propulsion force | a push or pull that causes an object to move |
| iterate | to preform repitions to improve on a process |
| system | a set of parts so related or interconnected that they work as a whole |
| fair test | a test in which only one factor (variable)is changed and all other conditions are kept the same |
| elapsed time | the time it takes to travel between a starting point and an ending point |
| balanced force | forces oppisite in direction and equal in magnitude; balanced forces have a net force of zero |
| frame of reference | the view from which you judge the motion of another object |
| quativitive data | information descibing the qualities of objects observed,but not measured |
| critera | goals that must be satisfied to be able to sucess achive a challenge |
| axles | round shalfs that connect the opposing wheels of a car |
| speed | a measure of how fast an object is traveling |
| gravity | the force of attraction between objects.on earth,gravity pulls object downward toward earth's center |
| baseline | a specific value or values that can serve as basis for compaison |
| accleration | a change over time in the speed,the direction,or the speed and direction, of motion |
| scale | the ratio of the measurements in a represtion or model of an object to the actual object |
| subsystem | a system within a system that has its own funtion |
| magintude | greatness or extent of size |
| unbalanced forces | forces that do not produce a net force of zero |
| design engineer | design and build a vehicle that will go straight,far,and fast,and carry a load |
