Answer 1

Ι = Cmr²

Question 1

what are the equations relating motion of a particle to angular motion of a particle?

Answer 1

v = ωr
a = αr
τ = Ια
KE = 1/2 Ιω²

Question 2

What are the equations for circular motion?

Answer 2

F = (mv²)/r
α = v²/r

Question 3

What is the equation for the inertial mass of a disc, a hoop and a sphere?

Answer 3

Hoop: I = mr²
Disc: I = (1/2)mr²
Sphere: I = (2/5)mr²
