一、汽车在转直角弯时前后轮的运动轨迹分析大家知道,当汽车前后轮运动方向一致时,汽车作直线运动;当汽车前后轮运动方向不一致时,会产生一个向心力,迫使汽车作曲线运动;当汽车前后轮运动方向不一致且方向偏差保持不变,产生向心力将保持不变,这时汽车会作圆周运动。这时圆的半? First, the car turns the corner before and after the turn of the track Analysis We all know that when the car is moving in the same direction before and after the wheel, the car for linear motion; when the car before and after the wheel is not the same direction of movement, will have a centripetal force, forcing the car curve ; When the car before and after the wheel is not the same direction of motion and the direction of the deviation remains unchanged, the resulting centripetal force will remain unchanged, then the car will make a circular motion. At this time round half?
