Question

derive the three equation of rotational motion under constant acceleration from first principle​

Answer 1

Explanation:

We use the equation ω=dθdt; since the time derivative of the angle is the angular velocity, we can find the angular displacement by integrating the angular velocity, which from the figure means taking the area under the angular velocity graph. In other words: ∫θfθ0dθ=θf−θ0=∫tft0ω(t)dt.
