047. game physics: simulating gravity and collisions (ks4)
Uncover the maths behind your favourite games by learning how physics engines model gravity, collisions, and movement in virtual worlds.
When a character jumps in a video game and falls back to the ground, what makes that happen? It is all down to the physics engine. Game developers use mathematical models to simulate the real world. Today, we will uncover how computers calculate gravity, velocity, and collisions, allowing you to bring realistic physics to your own virtual creations.
