ROTATIONAL MOTION MCQ Quiz: GKFix - Bridge of Knowledge - Page 92

Question 456

▼

Why does a spinning top precess when tilted?

Because it loses energy
Because friction stops it
Because gravity applies a torque that changes the direction of angular momentum
Because mass decreases

Question 457

▼

What is the condition for a body to have stable rotation about an axis?

Any axis is stable
Only vertical axis is stable
The axis must be a principal axis of inertia
Stability depends on color

Question 458

▼

How does the angular momentum of two identical particles moving in opposite directions on a ring compare?

They cancel completely
They double linear momentum
Their axial components add, but transverse components cancel if symmetric
They create heat

Question 459

▼

Why is the term 'fixed axis' important in the context of rotational angular momentum?

It reduces mass
It increases speed
It allows simplification by defining a constant direction for axial quantities
It changes color

Question 460

▼

What is the main advantage of using vector notation in angular momentum analysis?

It simplifies mass calculation
It reduces number of variables
It allows proper handling of direction and superposition
It eliminates time
