Answer:
The Second equation of rotational motion is θ = ω't +
Explanation:
Considering an object revolving in a circular path, then
Angular velocity (ω) = dθ/dt
θ is the angular displacement and t is the time.
Then, ω.dt = dθ
Since, ω = (ω' + ) { This is the first equation of rotational motion }
Now, we replace ω with (ω' + ) and we get,
(ω' + )dt = dθ
Integrating both sides, we have,
(ω' + )dt = dθ
Integrating these,
we integrate ω' from the limits 0 to T
we integrate from the limits 0 to T
And we integrate dθ from the limits 0 to θ
After Integrating these, we get :
θ = ω't +
Thus, the second equation of rotational motion is θ = ω't +
