2. A small sphere attached to a light rigid rod rotates about an axis perpendicular to and fixed to the other end of the rod. Relative to the positive direction of the axis of rotation, the angular positions of the sphere are negative, its angular velocity is negative, and its angular acceleration is positive. The sphere is a. rotating clockwise and slowing down. b. rotating counterclockwise and slowing down. c. rotating...

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...

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.25 kg m2 about its central axis, is set spinning counterclockwise (which may be taken as the positive direction) at 181 rev/min. The second disk, with rotational inertia 7.95 kg.m2 about its central axis, is set spinning counterclockwise at 879 rev/min. They then couple together. (a)...

Red-headed Agama lizards (Agama agama) are able to control the pitch of their bodies when jumping to higher ground or onto vertical surfaces by using their tail to regulate angular momentum. Pitch refers to, for example, the up or down orientation of the nose of an airplane or, in this case, the body and nose of the lizard. The fiqure below shows the lizard just before it jumps. A change in pitch during the jump would represent a rotation of...
