As we know that the three equation of a linear motion are
- (I) v = u+at
- (II) s = ut+1/2at²
- (III) v² = u²+2as
Where, the symbols have their usual meaning.
In the similar way, we can write equations of motion for rotational motion such as
- (I) ω = ω₀+αt
- (II) θ = ω₀t+1/2αt²
- (III) ω² = ω₀²+2α(θ-θ₀)
Where, θ₀ and ω₀ are the initial angular displacement and initial angular velocity of the body, respectively.
