Sure! Here's an example of a simple ball physics game implemented using JavaScript and presented as a single HTML file:

In this game, a red ball is displayed on the canvas and moves around based on its speed properties (`ballSpeedX` and `ballSpeedY`). The ball bounces off the walls of the canvas when it reaches the edges. The game loop continuously updates the ball's position and renders it on the canvas, creating the illusion of movement. To play the game on a smartphone, you can open the HTML file in a web browser on your device. The ball will move as the game loop runs, and you can watch its motion on the canvas.
