单摆模拟器(周期·角度·阻尼)

拖动重物后松开,它就会从那个角度开始摆动。按下「重置」,它会回到初始角度 的位置并停住。

匀变速直线运动模拟器Slope is acceleration, area is displacementYou can solve it without the timeA negative acceleration is not always a slowdownFalling and throwing upward are one motion
斜抛运动模拟器Horizontal and vertical move separatelyWhat disappears is the timeThe farthest throw is at 45°
摩擦模拟器Friction does as it is toldIt is set by how hard the surface is pressedThe angle of slipping does not depend on weight
靠墙杆模拟器Balanced forces can still topple itThe wall is smooth, the floor is roughThe more upright, the safer
滑轮模拟器Add the equations and the tension goesTension is not the weightIt takes weight to get it moving
过山车模拟器The path makes no differenceHeavy in the valley, light on the hillIt takes two and a half times the height
动量守恒定律模拟器Impulse changes momentumThey cancel on the insideThe second equation is the restitution
碰撞模拟器The wall carries the momentum offEvery bounce multiplies it by e²Infinitely many bounces, and it stops
圆周运动模拟器Constant speed and still acceleratingThere is no such force as centripetal forceThe flatter it lies, the faster it turns
弹簧振子模拟器Simple harmonic motion is a circle's shadowVelocity and acceleration are shadows tooEnergy only changes its form
单摆模拟器A small swing is the same as a springHeight decides the speedIn an accelerating train the vertical tilts
行星运动模拟器The Moon is falling tooThe nearer in, the fasterThe period is set by the size of the orbitFast enough and it never returns
