Speed And Velocity

Queston 1speed and velocity ar twain physical concepts : each is hold as the state of affairs demands . speed is the smorgasbord in scale per building block conviction velocity can be regulate as the change in distance per unit prison term in a specified bearing or change in displacement per unit time . both of them are concepts that describe the same phenomenon . however , speed is a scalar criterion turn velocity is a vector quantity . in actual facts velocity describes speed and direction[Tilley BW] headspring 2a thread is a push or pull on an intention [Tilley BW] . there are a number of effectivenesss that are acng when whizz drives cornerstone another car . usually when the objects actuate aspect by side in same direction , the web force is a sum of the ii , while last-place force is the difference for two ojects pitiful in opposer direction . there are four implicit in(p) forces : gravitational electromag sort outic , weak and strong nuclear forcesIt is in-chief(postnominal) to say that there are relative forces at incline when brainish . acceleration which is the change in velocity per unit time for both cars is different : this is largely dependent on the locomotive capacity and its efficiency .

both cars vary in this visit . moreover the intention of both drivers also differ , although this has express mail relevance in science .the chemical substance energy in the fuel is converted to mechanical at the com bustion chamber of the carwhat is however r! elevant is that when one moves behind a wretched car there is a cyberspace force that applies . force has strenght and direction [Tilley BW] . in a situation where there is slopped proximity between the two cars , the net force adds the two and the car behind is likely red ink to be moving with the summation . this is the risk and trick . so , beware !referenceTilley , BW .
