Learning Goal:
To understand and apply the formula
τ=Iα to rigid objects rotating about a
fixed axis.
To find the acceleration a of a particle of mass
m, we use Newton's second law: F⃗
net=ma⃗ , where F⃗ net is the net force
acting on the particle.
To find the angular acceleration α of a rigid object
rotating about a fixed axis, we can use a similar formula:
τnet=Iα, where τnet=∑τ
is the net torque acting on the object and...

Calculate the angular momentum for a rotating disk, sphere, and rod. (a) A uniform disk of mass 16 kg, thickness 0.5 m, and radius 0.9 m is located at the origin, oriented with its axis along the y axis. It rotates clockwise around its axis when viewed from above (that is, you stand at a point on the +y axis and look toward the origin at the disk). The disk makes one complete rotation every 0.7 s. What is the...
