Revision Notes — System of Particles and Rotational Motion

Key concepts, formulas, and definitions from System of Particles and Rotational Motion for AP EAPCET Physics preparation.

Key Topics to Revise

1

Center of Mass

  • Center of mass is the point where entire mass of the system appears to be concentrated
  • For two particles: x_CM = (m₁x₁ + m₂x₂)/(m₁ + m₂)
  • For n-particle system: R_CM = Σmᵢrᵢ/M where M is total mass
2

Angular Velocity and Angular Momentum

  • Angular velocity ω is rate of change of angular position
  • Relation between linear and angular velocity: v = ω × r
  • Angular momentum L = r × p = mvr sin θ
3

Torque and Rotational Dynamics

  • Torque τ = r × F is rotational analog of force
  • τ = rF sin θ = r⊥F = rF⊥
  • Net torque equals rate of change of angular momentum: τ = dL/dt
4

Moment of Inertia

  • Moment of inertia I is rotational analog of mass
  • For particles: I = Σmᵢrᵢ²
  • For continuous bodies: I = ∫r² dm
