How do I simulate a bouncing ball?

Open this page and use the live Blackbody & Radiation tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a bouncing ball from your own measurements.

Planck's law · Wien's displacement

Controls

Every warm object glows with a Planck spectrum. Heat it up and the peak shifts to shorter (bluer) wavelengths — that's why stars range from red to blue-white.

Temperature (K)

▶ Run in Python

Temperature5778 K

Peak wavelength502 nm

Colorwhite/yellow

Governing equation

λ_{m a x} = \frac{b}{T} = \frac{2.898 \times 1 0 ^{6}}{5778} = 502 nm

Reading this result: At 5778 K the Planck curve peaks at 502 nm, inside the visible band — Wien's law makes peak wavelength ∝ 1/T, so doubling the temperature halves the peak wavelength and shifts the glow toward blue.

About this simulation

The full Blackbody & Radiation tool models a bouncing ball with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
