摘要
讨论了地面对汽车车轮的摩擦力在转动能与平动能间的转化过程中所起的作用．对汽车的牵引力问题进行了分析．最后，从能量的观点给出了汽车不打滑条件．
This paper didcusses the function of motor-car wheels′ frictional force in course of conversion of energy between rotation and translation on the ground. It also analyses motor-car′s drawing force. Finally,the paper gives the condition that motor-car doesn′t slide on the ground from the view of energy.
