How to Play
1. Click on force buttons to add forces to the object.
2. For each force, select the correct angle as specified in the challenge.
3. The free body diagram will update in real-time.
4. You must add all required forces with their correct angles to complete the level.
Angle Guide (True Bearing):
- 0° = North (up) ↑
- 90° = East (right) →
- 180° = South (down) ↓
- 270° = West (left) ←
- 30°, 45°, 60° = Angles between North and East
- 120°, 135°, 150° = Angles between East and South
- 210°, 225°, 240° = Angles between South and West
- 300°, 315°, 330° = Angles between West and North
Important: Gravity always points downward (180°) and cannot be changed.
Tip: For inclined planes, normal forces are perpendicular to the surface, while friction acts parallel to the surface.
