ROTATIONAL MOTION MCQ Quiz: GKFix - Bridge of Knowledge

Question 501

▼

Why is the vector OC × v perpendicular to the fixed axis of rotation?

Because OC is zero
Because v is parallel to the axis
Because it opposes gravity
Because OC lies in a radial plane and v is tangential, making their cross product axial

▼

In the expression l = r × p, what does the symbol 'p' represent?

▼

What is the primary reason for separating angular momentum into L_⊥ and L_z components in rotational motion?

To calculate linear speed
To distinguish between axial and transverse contributions to total angular momentum
To determine gravitational effects
To measure temperature changes

▼

How is the velocity vector oriented relative to CP in circular motion?

▼

What is the consequence of choosing a non-symmetric axis for rotation?
