Acceleration
Classical Mechanics
m/s²
The vector rate of change of velocity with respect to time.
a = dv/dt = d²r/dt²
Amplitude
Classical Mechanics
m
The maximum magnitude of displacement from the equilibrium position in an oscillating or wave system.
A = x_max
Angular Acceleration
Classical Mechanics
rad/s²
The rate of change of angular velocity with respect to time.
α = dω/dt = τ / I
Angular Displacement
Classical Mechanics
rad (radians)
The angle through which a point or line rotates about a specified axis in a specified direction.
θ = s / r
Angular Momentum
Classical Mechanics
kg·m²/s (J·s)
The rotational analog of linear momentum, defined as the product of moment of inertia and angular velocity.
L = I ω = r × p
Angular Velocity
Classical Mechanics
rad/s
The vector rate of change of angular displacement with respect to time.
ω = dθ/dt
Apparent Weight
Classical Mechanics
N
The effective weight of a body, equal to the normal contact force supporting it in an accelerating frame.
W_app = m (g + a)
Archimedes' Principle
Classical Mechanics
N
The principle stating that any object fully or partially submerged in a fluid experiences an upward buoyant force equal to the weight of displaced fluid.
Fb = m_fluid g = ρ_fluid V_displaced g
