拐弯与向心力当你骑自行车急速拐弯时,人和车身都要向弯道内侧倾斜.这是因为要使物体做圆周运动,一定要给物体一个向着圆心的力,这个力叫做向心力.杂技演员在表演摩托车沿着圆桶形的峭壁疾驶时,人和车身倾斜得几乎与水平方向平行.这种倾斜是为了提供足够的向心力,保证人和车能? Turning and Centripetal Forces When you make a sharp turn on a bicycle, both the person and the body must lean toward the inside of the curve. This is because to make the object do a circular motion, it is necessary to give the object a force toward the center of the circle. This force is called centripetal force. Acrobats When a motorbike sprints along a barrel-shaped cliff, people and body are tilted almost parallel to the horizontal direction. This inclination is to provide enough centripetal force to guarantee people and cars?
