Classical Mechanics
m, rad/s
Repetitive periodic motion where restoring force is directly proportional to displacement and acts toward the equilibrium position.
x(t) = A cos(ω t + φ), ω = √(k/m)
Simple Machine
Classical Mechanics
Dimensionless
A basic mechanical device that changes the direction or magnitude of an applied force.
MA = F_out / F_in
Static Equilibrium
Classical Mechanics
N, N·m
The state of a rigid body where both net external force and net external torque are zero, keeping the body completely at rest.
∑ F = 0, ∑ τ = 0
Stokes' Law
Classical Mechanics
N
A mathematical law expressing viscous drag force experienced by small spherical particles moving at low speeds through a viscous fluid.
