Simulador de órbitas planetarias: gravitación, elipse y leyes de Kepler

Arrastra sobre la pantalla para fijar la velocidad y la dirección de lanzamiento, y suelta para que el planeta salga a recorrer su órbita. Si tiras poco, cae en una elipse estrecha; si tiras lo bastante, se aleja de la estrella y ya no vuelve.

Órbitas planetarias

Simulador de movimiento uniformemente acelerado Slope is acceleration, area is displacement You can solve it without the time A negative acceleration is not always a slowdown Falling and throwing upward are one motion

Simulador de tiro parabólico Horizontal and vertical move separately What disappears is the time The farthest throw is at 45°

Simulador de rozamiento Friction does as it is told It is set by how hard the surface is pressed The angle of slipping does not depend on weight

Simulador de barra apoyada Balanced forces can still topple it The wall is smooth, the floor is rough The more upright, the safer

Simulador de poleas Add the equations and the tension goes Tension is not the weight It takes weight to get it moving

Simulador de montaña rusa The path makes no difference Heavy in the valley, light on the hill It takes two and a half times the height

Simulador de conservación del momento Impulse changes momentum They cancel on the inside The second equation is the restitution

Simulador de choques The wall carries the momentum off Every bounce multiplies it by e² Infinitely many bounces, and it stops

Simulador de movimiento circular Constant speed and still accelerating There is no such force as centripetal force The flatter it lies, the faster it turns

Simulador de péndulo elástico Simple harmonic motion is a circle's shadow Velocity and acceleration are shadows too Energy only changes its form

Simulador de péndulo simple A small swing is the same as a spring Height decides the speed In an accelerating train the vertical tilts

Simulador de órbitas planetarias The Moon is falling too The nearer in, the faster The period is set by the size of the orbit Fast enough and it never returns
