Marble Maze

This simulation shows how a ball accelerates on a slope. Students tilt an 11 by 11 cell maze by dragging or using arrow keys, and the ball speeds up along the incline, bounces off walls with some energy loss and slows with rolling friction. Readouts show time, best time, falls and current tilt. Sliders change rolling friction and maximum tilt, and a toggle switches drag between tilting the board and orbiting the view. Teachers can connect it to acceleration on inclines and to fine motor control.

• Drag gently to tilt the board and roll the ball toward the green hole, avoiding black holes.
• Watch the Tilt readout and notice that a bigger tilt makes the ball speed up faster.
• Raise Rolling friction and see how the ball stops sooner on a level board.
• Switch off Drag tilts the board and use arrow keys while orbiting the view with the mouse.
• Lower Max tilt to 8 degrees, then try to beat your Best time.

1. 1Describe how tilt angle affects a ball's acceleration.
2. 2Explain why a ball slows down on a level surface.
3. 3Relate wall bounces to energy being lost.
4. 4Use time and fall counts to refine a control strategy.
