01Sound

Sound studio

Suggested-level exploration

Change a pure tone’s frequency and amplitude, and compare a speaker’s motion with what you hear. The vibration is shown in slow motion so it can be inspected. Optional audio plays a short synthesised tone, not a recording of a real bird or instrument.

02Forces

Push against friction

Suggested-level exploration

Apply a horizontal push to a block initially at rest. This simplified model uses one friction threshold: below it, static friction matches the push; above it, friction is capped at that value. It illustrates force balance, not a full material simulation.

03Forces

Pressure

Suggested-level exploration

The same force can produce different pressures depending on contact area. Here the force is perpendicular to the surface and spread uniformly.
