Mode d'emploi

Simulateur de pendule simple – période, angle, amortissement

Faites glisser la masse et relâchez-la pour qu'elle se mette à osciller depuis cet angle. « Réinitialiser » la ramène à l'angle initial et l'y arrête.

Simulateur de mouvement uniformément accéléré 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

Simulateur de tir parabolique Horizontal and vertical move separately What disappears is the time The farthest throw is at 45°

Simulateur de frottement 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

Simulateur d'échelle appuyée Balanced forces can still topple it The wall is smooth, the floor is rough The more upright, the safer

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

Simulateur de montagnes russes The path makes no difference Heavy in the valley, light on the hill It takes two and a half times the height

Simulateur de conservation de la quantité de mouvement Impulse changes momentum They cancel on the inside The second equation is the restitution

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

Simulateur de mouvement circulaire Constant speed and still accelerating There is no such force as centripetal force The flatter it lies, the faster it turns

Simulateur de pendule élastique Simple harmonic motion is a circle's shadow Velocity and acceleration are shadows too Energy only changes its form

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

Simulateur d'orbite planétaire 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
