Homework Answers
When we consider a moving body in mechanical equilibrium that means there is no resultant force and torque.
Now linear and angular momentum will be constant.
so, linear and angular velocities will be constant.
1. The object's linear speed is a constant. True
2. If the object is rotating, it must be rotating about an external, fixed point. True
3. The object's direction is not changing. True
4. If the object is rotating, its rotational speed must be constant. True

Learning Goal: To learn the definition andapplications of angular momentum including its relationship totorque. By now, you should be familiar with the concept ofmomentum, defined as the product of an object's mass andits velocity: . You may have noticed that nearly every translationalconcept or equation seems to have an analogous rotationalone. So, what might be the rotational analogue of momentum? Just as the rotational analogue of force , called thetorque , isdefined by the formula , the rotational analogue of...

In this problem we consider rotational motion of a diatomic molecule such as carbon monoxide or nitric oxide. We treat a system of two point masses, mi and m2, rotating about their common center of mass. There are no external forces or torques on the system. We are in the center-of-mass frame, so the CM is at the origin. We treat the case of steady rotation, with w pointing in the z direction, and the particles moving in the ry...

When we talk about rigid-body rotation, the concept of a perfectly rigid body can only be an idealization. In reality, any object will compress, expand, or deform to some extent when subjected to the strain of rotation. However, if we let it settle down for a while, perhaps it will reach a new equilibrium. As an example, suppose we fill a centrifuge tube with some compressible substance like shaving cream or Wonder Bread. We can model the contents of the...
