STAGE 2 PHYSICS THE PHYSICS OF CAR RACING INTRODUCTION Physics is the science of measurement. ... If a car is moving at a constant speed or velocity, v, then the distance, s, it travels in time, t, is s = vt or velocity times time. This equation really expresses nothing more than the definition of velocity, and is the basis of car racing. ... This sideways acceleration is a change in the sideways velocity. ...
