向心力

Une balle accrochée par un fil tourne autour d'un axe. La force centripète est exercée par le fil sur la balle pour la maintenir en rotation sur la trajectoire spécifiée. C'est cette force qui donne au fil sa tension.

在古典力学中,向心力是当物体沿着圆周或者曲线轨道运动时,指向圆心(曲率中心)的合外力作用力。“向心力”一词是从这种合外力作用所产生的效果而命名的。这种效果可以由弹力、重力、摩擦力等任何一力而产生,也可以由几个力的合力或其分力提供。

因为圆周运动属于曲线运动,在做圆周运动中的物体也同时会受到与其速度方向不同的合外力作用。对于在做圆周运动的物体,向心力是一种拉力,其方向随着物体在圆周轨道上的运动而不停改变。此拉力沿着圆周半径指向圆周的中心,所以得名“向心力”。向心力指向圆周中心,且被向心力所控制的物体是沿着切线的方向运动,所以向心力必与受控物体的运动方向垂直,仅产生速度法线方向上的加速度。因此向心力只改变所控物体的运动方向,而不改变运动的速率,即使在非匀速圆周运动中也是如此。非匀速圆周运动中,改变运动速率的切向加速度并非由向心力产生。

Centripetal force 向心力

A body experiencing uniform circular motion requires a centripetal force, towards the axis as shown, to maintain its circular path.
Vector relationships for uniform circular motion; vector Ω representing the rotation is normal to the plane of the orbit with polarity determined by the right-hand rule and magnitude dθ /dt.
Upper panel: Ball on a banked circular track moving with constant speed v; Lower panel: Forces on the ball
Velocity and acceleration for nonuniform circular motion: the velocity vector is tangential to the orbit, but the acceleration vector is not radially inward because of its tangential component aθ that increases the rate of rotation: dω / dt = | aθ| / R.

A centripetal force (from Latin centrum "center" and petere "to seek") is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as "a force by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre". In Newtonian mechanics, gravity provides the centripetal force responsible for astronomical orbits.
