🌀 Rotational Dynamics

Explore torque, angular momentum, and rotational motion

Difficulty: ● Hard

📐 Physics Formulas
τ = r × F
Torque
I = Σ m × r²
Moment of Inertia
L = I × ω
Angular Momentum
α = τ / I
Angular Acceleration
📚 Key Concepts
  • Torque causes angular acceleration
  • Mass farther from center = higher inertia
  • Angular momentum is conserverd
  • Friction opposes rotational motion
  • Energy converts between rotational and translational
🔬 Try This
  • Add masses at different radii
  • Compare rotation with masses near vs far
  • Apply torque and observe acceleration
  • Try with aand without friction
  • Watch inertia change with distribution
