this experience, we'll understand the “rotational analog” with the linear motion. We use s to stand for the linear quantities like θ stand for the angular distance, and ω stand for the velocity in angular, and α represent the angular acceleration. Which gives the relationship of s=rθ, v=rω, and a=rα. I is the angular mass(inertia) and L is the momentum and τ represent force to the force. So in order to calculate the angular distance, velocity, acceleration, we need to use it to divide by the radius of the circular path. Then we can develop with the inertia equals to mass of particle times square of radius. The moment of inertia is the angula mass I=mr^2 . For the angular momentum L which is equals to rp and torque( τ ) equals to rF. Or we can also expressions for angular momentum and torque in: p=mv L=Iω, and F=ma τ=Iα, To calculate the moment of inertia I we use the formula: I = mr ( g ra net ) | a fr | + a net , it derive: τ net = τ

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
