ROTATIONAL MOTION MCQ Quiz: GKFix - Bridge of Knowledge - Page 67

Question 331

▼

In pure translational motion, how do the velocities of different particles of the body compare?

Velocities increase with distance from center
Velocities are random
Only the center moves
All particles move with the same velocity at any instant

Question 332

▼

What is the nature of motion for a rigid body not fixed in space?

It can only rotate
It can only translate
It vibrates in place
It can have pure translation or a combination of translation and rotation

Question 333

▼

What determines the plane of motion for a particle in a rigid body rotating about a fixed axis?

The plane is parallel to the axis
The plane is at 45 degrees to the axis
The plane is tangential to the axis
The plane is perpendicular to the axis of rotation

Question 334

▼

What happens to the angular speed of a rotating system when its moment of inertia increases without external torque?

Angular speed increases
Angular speed remains unchanged
Angular speed becomes zero
Angular speed decreases

Question 335

▼

How does a diver use the principle of conservation of angular momentum during a dive?

By increasing body mass
By pushing against air
By changing body shape to increase drag
By tucking the body to reduce moment of inertia and increase rotation speed
