Radius of Gyration
Classical Mechanics
m
The radial distance from a rotation axis at which total mass could be concentrated without altering the moment of inertia.
k = √(I / m)
Range
Classical Mechanics
m
The total horizontal distance traveled by a projectile from launch to landing at the same vertical height.
R = (v0² sin 2θ) / g
Restoring Force
Classical Mechanics
N
A force that acts to bring a body back toward its stable equilibrium position whenever it is displaced.
F = -k x
Reynolds Number
Classical Mechanics
Dimensionless
A dimensionless quantity in fluid mechanics predicting flow patterns, equal to ratio of inertial forces to viscous forces.
Re = (ρ v L) / η
Rotational Kinetic Energy
Classical Mechanics
J
The kinetic energy possessed by a body due to its rotation about an axis.
