Come usare

Simulatore di asta appoggiata – attrito statico, angolo critico, momento

Trascina l'estremità inferiore dell'asta per cambiare l'angolo che forma con il pavimento. La parete è liscia, quindi a trattenere l'asta è solo l'attrito al pavimento.

Simulatore di moto uniformemente accelerato 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

Simulatore di moto del proiettile Horizontal and vertical move separately What disappears is the time The farthest throw is at 45°

Simulatore di attrito 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

Simulatore di asta appoggiata Balanced forces can still topple it The wall is smooth, the floor is rough The more upright, the safer

Simulatore di carrucola Add the equations and the tension goes Tension is not the weight It takes weight to get it moving

Simulatore di montagne russe The path makes no difference Heavy in the valley, light on the hill It takes two and a half times the height

Simulatore di conservazione della quantità di moto Impulse changes momentum They cancel on the inside The second equation is the restitution

Simulatore di urti The wall carries the momentum off Every bounce multiplies it by e² Infinitely many bounces, and it stops

Simulatore di moto circolare Constant speed and still accelerating There is no such force as centripetal force The flatter it lies, the faster it turns

Simulatore di pendolo elastico Simple harmonic motion is a circle's shadow Velocity and acceleration are shadows too Energy only changes its form

Simulatore di pendolo semplice A small swing is the same as a spring Height decides the speed In an accelerating train the vertical tilts

Simulatore di orbite planetarie 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
