## Summary of Rotational motion

## Rotational quantityAngular displacement
Angular velocity Angular acceleration Torque Angular momentum Rotational inertia Rotational energy |
## DefinitionChange in angular orientation
Rate of change of angular displacement Rate of change of angular velocity Turning force on an object "Amount" of rotational motion Resistant of an object to rotational motion |
## Relate to rotational-
ω = θ/t α = Δω/t τ = I α L = I ω |
## Translational analogueθ = d/r
ω = v/r α = a/r τ = F r L = m v r |
