The Collision Lab simulation allows students to investigate collisions in 1D and 2D. Experiment with the number of objects and initial conditions. Vary the elasticity to explore inelastic collisions. https://phet.colorado.edu/en/simulations/collision-lab/

TIL: Conservation of energy is a simplification. On a cosmological scale, energy is _not_ conserved.

How Noether’s Theorem Revolutionized Physics | Quanta Magazine

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics.

Energy Forms and Changes

Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users. Track and visualize how energy flows and changes through your system.

#SabineHossenfelder - How the #GreenhouseEffect Really Works

"#GreenhouseGases prevent infrared radiation from escaping to outer space. This warms the surface of #Earth. More #GreenhouseGas means more warming. Alas if you look at the numbers it turns out most infrared radiation is absorbed almost immediately above the ground already at pre-industrial greenhouse gas levels."
