포물선 운동 시뮬레이터 (포물선 궤도·발사각·도달 거리)

화면을 오른쪽 위로 끌면 초기 속도와 발사각이 정해지고, 놓으면 공이 날아갑니다. 끈 길이가 그대로 속도의 크기, 방향이 그대로 발사각입니다.

등가속도 직선 운동 시뮬레이터Slope is acceleration, area is displacementYou can solve it without the timeA negative acceleration is not always a slowdownFalling and throwing upward are one motion
포물선 운동 시뮬레이터Horizontal and vertical move separatelyWhat disappears is the timeThe farthest throw is at 45°
마찰 시뮬레이터Friction does as it is toldIt is set by how hard the surface is pressedThe angle of slipping does not depend on weight
기대어 세운 막대 시뮬레이터Balanced forces can still topple itThe wall is smooth, the floor is roughThe more upright, the safer
도르래 시뮬레이터Add the equations and the tension goesTension is not the weightIt takes weight to get it moving
롤러코스터 시뮬레이터The path makes no differenceHeavy in the valley, light on the hillIt takes two and a half times the height
운동량 보존 법칙 시뮬레이터Impulse changes momentumThey cancel on the insideThe second equation is the restitution
충돌 시뮬레이터The wall carries the momentum offEvery bounce multiplies it by e²Infinitely many bounces, and it stops
원운동 시뮬레이터Constant speed and still acceleratingThere is no such force as centripetal forceThe flatter it lies, the faster it turns
용수철 진자 시뮬레이터Simple harmonic motion is a circle's shadowVelocity and acceleration are shadows tooEnergy only changes its form
단진자 시뮬레이터A small swing is the same as a springHeight decides the speedIn an accelerating train the vertical tilts
행성 운동 시뮬레이터The Moon is falling tooThe nearer in, the fasterThe period is set by the size of the orbitFast enough and it never returns
