We'll focus on ensuring that the vector's direction matches the planet's actual velocity.\n\nHere's how we can adjust the `display` method of the `Planet` class to address the issue:\n\n```javascript\n// Planet.js\nclass Planet {\n constructor(name, x, y, m, hue, id, vx = 0, vy = 0, image = null, emoji = '') {\n this.name = name;\n this.x = x;\n this.y = y;\n this.vx = vx;\n this.vy = vy;\n this.ax = 0;\n this.ay = 0;\n this.frictionVector = null;\n this.radius = m;\n this.mass = m;\n this.hue = hue;\n this.color = color(this.hue, 100, 50);\n this.id = id;\n this.image = image;\n this.emoji = emoji;\n\n currentHue += 35;\n currentHue = currentHue % 360;\n }\n\n move() {\n this.vx += this.ax;\n this.vy += this.ay;\n this.x += this.vx;\n this.y -= this.vy;\n }\n\n display() {\n push();\n translate(this.x, this.y);\n\n if (this.image) {\n imageMode(CENTER);\n image(this.image, 0, 0, this.radius * 2, this.radius * 2);\n } else if (this.emoji) {\n textSize(this.radius * 2);\n textAlign(CENTER, CENTER);\n text(this.emoji, 0, 0);\n } else {\n fill(this.color);\n ellipse(0, 0, this.radius * 2, this.radius * 2);\n }\n\n pop();\n\n // Draw the velocity vector\n if (this.vx !== 0 || this.vy !== 0) {\n let velocityVector = createVector(this.vx, -this.vy).mult(2); // Scale for visibility\n drawArrow(createVector(this.x, this.y), velocityVector, '#21f00a'); // Draw the velocity arrow\n }\n\n // Draw the acceleration vector\n if (this.ax !== 0 || this.ay !== 0) {\n let accelerationVector = createVector(this.ax, -this.ay).mult(20); // Scale for visibility\n drawArrow(createVector(this.x, this.y), accelerationVector, '#035afc'); // Draw the acceleration arrow\n }\n }\n\n // ... existing methods ...\n}\n```\n\n### Key Changes:\n- **Velocity Vector Calculation**: When creating the velocity vector, the y-component is negated (`-this.vy`) to match the coordinate system used for drawing, which can sometimes be inverted.\n- **Ensuring Accurate Display**: The vectors are now correctly calculated and displayed in relation to the planet's position.\n\nThis should make the velocity vectors display in the correct direction relative to the planet's movement.
