Key Equations
Kinematics: v = v₀ + at · x = x₀ + v₀t + ½at² · v² = v₀² + 2aΔx
Newton's 2nd: ΣF = ma
Friction: f_s ≤ μ_sN · f_k = μ_kN
Centripetal: a_c = v²/r
Gravitation: F = Gm₁m₂/r² · g = GM/r²
Work: W = Fd cosθ · W_net = ΔK
Kinetic energy: K = ½mv²
Potential energy: U_g = mgh · U_s = ½kx²
Power: P = W/t = Fv
Momentum: p = mv · J = FΔt = Δp
Spring period: T = 2π√(m/k)
Pendulum period: T = 2π√(L/g)
Torque: τ = rF sinθ · τ_net = Iα
Rotational K: K = ½Iω²
Angular momentum: L = Iω = mvr
Rolling: v = rω · K_total = ½mv² + ½Iω²
Constants & Moments of Inertia
- • g = 9.8 m/s² · G = 6.67×10⁻¹¹ N·m²/kg²
- • Point mass: mr² · Solid cylinder/disk: ½mr² · Hollow cylinder: mr² · Solid sphere: ⅖mr²
- • Rod about center: (1/12)mL² · Rod about end: (1/3)mL²
Exam Tips
- • Draw the free-body diagram first: every dynamics FRQ starts there
- • Momentum and energy are vectors and scalars respectively, keep directions straight
- • Check conservation laws before brute force: isolated system? → momentum; no friction? → energy
- • FRQ: claim + equation + substitution + units. Show the equation before numbers
- • Ratio questions: write the formula twice and divide. Constants cancel
