17. Angular Kinematics: Rotational Kinematics

Question 1

Define angular acceleration

Answer 1

Angular acceleration is a change in angular velocity overtime. (α = ∆ω/∆t)

Question 2

What are the 3 rotational kinematic equations?

Answer 2

1. ω = ω_o+αt
2. θ = ω_ot+½αt²
3. ω² = ω_o² + 2αθ

Question 3

There are Kinematic Equations for rotational motion similar to the ones we used for linear motion. In both cases, we must remember that…

Answer 3

the Acceleration MUST BE Constant
