Motion and Collisions Physics
index.html
In canvas animation, velocity describes how quickly and in what direction an object's position changes over time. Acceleration is the rate at which velocity itself changes—this allows for effects like speeding up or slowing down. A common form of acceleration is gravity, which constantly increases the downward velocity of an object, making its motion appear more realistic. By updating an object's position with its velocity, and its velocity with acceleration, you can simulate basic physics like falling, bouncing, or sliding.

By combining velocity, acceleration, and collision detection, you can build more complex and engaging animations. Extending these basic physics principles lets you simulate friction, elastic collisions, or even multiple interacting objects. As you add more rules, your canvas animations can become as realistic or imaginative as you like, supporting anything from bouncing balls to full-featured games.
1. What does velocity represent in the context of canvas animation physics?
2. What is a common way to detect a collision between a ball and the edge of the canvas?
