Accepted Answer

The net force on the object is zero and the net torque on the object is zero about any point.

Answer

All forces acting on the object are balanced, but the net torque does not need to be zero.

Answer

The net torque about the center of mass is zero, but the net force may be nonzero.

Answer

All forces acting on the object point in the same direction and are equal in magnitude.

Question 22

A solid cylinder and a hollow ring (thin hoop) have identical mass and radius. The rotational inertia of the solid cylinder is I = ½MR², and the rotational inertia of the hoop is I = MR². The same net torque is applied to each object about its central axis.

Which object has the greater angular acceleration?

Accepted Answer

The solid cylinder, because it has a smaller rotational inertia

Answer

The hollow ring, because its mass is concentrated farther from the axis

Answer

Both objects have the same angular acceleration, because they have the same mass and radius

Answer

The object with the larger radius, regardless of mass distribution

Question 23

A figure skater spins with arms extended. The skater then pulls both arms inward, reducing her rotational inertia. No external torques act on the skater during this motion.

What happens to the skater's angular velocity?

Accepted Answer

Angular velocity increases, because rotational inertia decreases while angular momentum is conserved.

Answer

Angular velocity decreases, because the skater's rotational inertia decreases.

Answer

Angular velocity remains the same, because angular momentum is conserved.

Answer

Angular velocity becomes zero, because the skater's arms are no longer contributing to rotation.

Question 24

Accepted Answer

The total angular momentum of a system is constant when no net external torque acts on the system.

Answer

The total angular momentum of a system is always constant, regardless of external influences.

Answer

Angular momentum is conserved only when no friction acts between surfaces in the system.

Answer

Angular momentum is equivalent to linear momentum for objects undergoing rotational motion.

Question 26

A satellite travels in an elliptical orbit around a planet. Observations show that the satellite moves faster when it is closer to the planet than when it is farther away.

Which of the following best explains this observation?

Accepted Answer

Conservation of angular momentum requires the satellite's orbital speed to increase as its orbital radius decreases.

Answer

The greater gravitational force when closer to the planet does more work on the satellite, increasing its speed.

Answer

The centripetal force increases near the planet, directly causing an increase in tangential speed.

Answer

Newton's third law requires the satellite to accelerate toward the planet at all times.

Question 27

A student doubles the amplitude of oscillation of a mass-spring system. How does this change the period of oscillation?

Accepted Answer

The period remains unchanged, because the period of a mass-spring system does not depend on amplitude.

Answer

The period doubles, because greater amplitude means the mass travels a longer path.

Answer

The period increases by a factor of &radic;2, because energy is proportional to amplitude squared.

Answer

The period is halved, because the restoring force increases with larger amplitude.

Question 28

A physics student investigates the factors that affect the period of a simple pendulum. Which of the following quantities does the period of a simple pendulum depend on?

Accepted Answer

The length of the pendulum and the local gravitational acceleration only

Accepted Answer

At the equilibrium position, where displacement is zero

Answer

At maximum displacement (amplitude), where the restoring force is greatest

Answer

At the midpoint between equilibrium and maximum displacement

Answer

Kinetic energy is constant throughout the motion because total energy is conserved
