Core Scientific Concepts

Electric Circuits

  • Battery → Motor → Motion

  • Components: battery holder, wires, switch, motor

  • Energy transfer from electrical to mechanical (vibration)

🌀 Vibrational Motion

  • Uneven spinning of motor shaft causes vibration

  • Vibration leads to directional, random, or circular movement

⚙️ Mechanical Systems & Robotics

  • Simple robotic system without coding

  • Basic design principles: balance, structure, friction, speed

🚀 Force & Motion

  • Newton’s Third Law: Action and reaction in vibration-based propulsion

  • Surface interaction and friction's effect on speed and direction
