Question 1611

▼

How does Newton’s third law ensure internal forces do not affect total torque?

They double the torque
They increase rotation
Internal forces act in equal and opposite pairs with zero net torque
They vanish

Question 1612

▼

Why is the moment of inertia not mentioned in the given text on equilibrium?

It is unimportant
The author forgot
The text focuses on force and torque balance, not rotational inertia
It is only for liquids

Question 1613

▼

What is the implication of constant angular momentum for a satellite in orbit?

It falls down
Its speed is always the same
Its areal velocity remains constant
It changes color

Question 1614

▼

How does the vector nature of torque affect rotational equilibrium?

Vectors are not important
It only matters in 2D
It requires balance in all three spatial directions
It reduces to scalar

Question 1615

▼

What is the role of the center of mass in rotational motion under external forces?

It resists all motion
It disappears under force
It moves as if all external forces act at that point
It spins always
