ROTATIONAL MOTION MCQ Quiz: GKFix - Bridge of Knowledge - Page 105

Question 521

▼

Why is the cross product used in angular momentum definition?

To add vectors
Because it measures speed
Because it captures rotational effects based on perpendicular components
To simplify calculations

Question 522

▼

What is the significance of the expression m r⊥² ω k̂?

Linear momentum
Kinetic energy
Torque
It represents the axial angular momentum of a particle

Question 523

▼

What is the effect of asymmetry on rotational stability?

Improves stability
No effect
It causes wobbling due to non-zero L_⊥
Reduces angular speed

Question 524

▼

What determines the direction of the angular velocity vector ω?

Mass distribution
Linear velocity
Direction of force
Right-hand rule based on rotation direction

Question 525

▼

How does the angular momentum of a particle differ from that of a rigid body?

They are identical
For translational motion only
For a rigid body, it is the sum of individual particle contributions
It depends only on center of mass
