While in the real world, we understand physics through math, in the world of video generation, an AI model that understands physics should be able to watch a sequence of frames and then predict which ...

3.1). As the ion travels through the solid, it undergoes collisions with the stationary target atoms, which deflect the ion from its initial direction. The ion also collides with electrons in the ...

This is the law of conservation of momentum. It is true for all collisions. Watch this video for a practical demonstration of conservation of momentum in elastic collisions.

This is an inelastic collision. If kinetic energy before is the same as after, the collision is elastic. Interactions between molecules are perfectly elastic collisions. In most other cases (eg ...
