Hi, I’m having trouble understanding how to apply physics to a `Phaser.GameObjects.Arc` object in Phaser. I’ve noticed that most tutorials focus on using sprites for physics, and I’m struggling with the documentation. I want to add physics methods to my `ball` object, which is of type `Phaser.GameObjects.Arc`. Specifically, I’d like to use methods like `setVelocity`, but they don’t seem to exist for the Arc type. Am I missing a step in the process?

Here’s the code snippet where I’m facing the issue:

```javascript
let ball: Phaser.GameObjects.Arc;

export function preload(this: Phaser.Scene) {
  // Preload logic here
}

export function create(this: Phaser.Scene) {
  ball = this.add.circle(100, 100, 20, 0x6666ff);
}

function update() {
  const initialVelocityX = 100;
  const initialVelocityY = 100;
  // Need to implement physics here
}

```

Any advice or guidance would be greatly appreciated. Thanks in advance!

```js
ball = this.add.circle(100, 100, 20, 0x6666ff);

// Creates `ball.body`:
this.physics.add.existing(ball);

ball.body.setVelocity(100, 100);

```
