I am writing a simple simulation of a ball rolling down an inclined plane. I drop the ball and it falls to the inclined plane. As it bounces a bit, it picks up speed on the plane until the point where it stops sliding and just rolls.
When it starts to roll, the ball will slow down a bit and then roll the rest of the way at a constant speed. From that point on it will not accelerate at all unlike a normal ball on a slope.
If I set friction to 0, it will accelerate, but the ball does not roll - it just slides down the slope which isn't what I want.
I modified a codepen to show a wireframe version of this: https://codepen.io/efunneko/pen/oNdGbVz
The ball creation is simply:
Composite.add(world, Bodies.circle(width / 1.2, height / 4, 40, {restitution: 0.5}));
