1A thin uniform ring (hoop) and a solid uniform disk both have the exact same total mass M and outer radius R. How do their moments of inertia about a central axis perpendicular to their plane compare?
A.The ring has twice the moment of inertia of the disk.
B.The disk has twice the moment of inertia of the ring.
C.Both objects have identical moments of inertia.
D.The ring has four times the moment of inertia of the disk.
Explanation: For a thin uniform ring of mass M and radius R, all mass is located at distance R from the central axis, giving I_ring = M*R^2. For a solid uniform disk, mass is continuously distributed from r = 0 to r = R, yielding I_disk = 0.5*M*R^2. Therefore, I_ring = 2 * I_disk.
2A heavy flywheel starts from rest and accelerates with a constant angular acceleration of 4.0 rad s^-2. What total angular displacement does the flywheel undergo during the first 5.0 s of motion?
A.50 rad
B.20 rad
C.100 rad
D.10 rad
Explanation: Using the rotational kinematic equation theta = omega_0*t + 0.5*alpha*t^2 with omega_0 = 0 rad s^-1, alpha = 4.0 rad s^-2, and t = 5.0 s: theta = 0.5 * 4.0 * (5.0)^2 = 0.5 * 4.0 * 25 = 50 rad.
3An object executing simple harmonic motion (SHM) has an amplitude of 0.20 m and a time period of 2.0 s. What is the maximum magnitude of acceleration experienced by the object?
A.1.97 m s^-2
B.0.63 m s^-2
C.3.95 m s^-2
D.0.31 m s^-2
Explanation: In SHM, the maximum acceleration magnitude occurs at maximum displacement (x = A) and is given by a_max = omega^2 * A. The angular frequency is omega = 2*pi / T = 2*pi / 2.0 = pi rad s^-1. Thus, a_max = pi^2 * 0.20 approx 9.8696 * 0.20 = 1.97 m s^-2.
4A figure skater spinning on frictionless ice pulls her arms inwards, reducing her moment of inertia to half its initial value (I_f = 0.5 * I_i). What happens to her rotational kinetic energy?
A.It doubles (E_k,f = 2 * E_k,i).
B.It remains unchanged.
C.It decreases by half.
D.It quadruples.
Explanation: By conservation of angular momentum (no net external torque), L = I_i * omega_i = I_f * omega_f. Since I_f = 0.5 * I_i, omega_f = 2 * omega_i. Rotational kinetic energy can be expressed as E_k = L^2 / (2*I). Because L is constant and I is halved, E_k doubles (E_k,f = 2 * E_k,i). Internal muscular work performed by the skater provides the additional kinetic energy.
5A satellite moves in a stable circular orbit around Earth at an orbital distance r from Earth's center. If the satellite's orbital radius is quadrupled to 4r, how does its orbital speed v change?
A.The orbital speed is halved (v_new = 0.5 * v).
B.The orbital speed quadruples.
C.The orbital speed is reduced to one-fourth.
D.The orbital speed doubles.
Explanation: Equating gravitational force to centripetal force yields G*M*m / r^2 = m*v^2 / r, which simplifies to orbital speed v = sqrt(G*M / r). If r becomes 4r, v_new = sqrt(G*M / (4r)) = 0.5 * sqrt(G*M / r) = 0.5 * v.
6A rigid spinning disk with moment of inertia I = 0.80 kg m^2 is rotating at 30 rad s^-1. What constant retarding torque must be applied to bring the disk to a complete stop in 4.0 s?
A.6.0 N m
B.24 N m
C.1.5 N m
D.9.6 N m
Explanation: The required angular deceleration magnitude is alpha = delta_omega / delta_t = (30 - 0) / 4.0 = 7.5 rad s^-2. Applying Newton's second law for rotation: torque tau = I * alpha = 0.80 * 7.5 = 6.0 N m.
7A simple pendulum of length L on Earth has a period T. If the length of the pendulum is quadrupled to 4L while keeping local gravitational acceleration g constant, what is the new period?
A.2T
B.4T
C.T/2
D.16T
Explanation: The period of a simple pendulum for small angles is given by T = 2*pi * sqrt(L / g). Replacing L with 4L yields T_new = 2*pi * sqrt(4L / g) = 2 * (2*pi * sqrt(L / g)) = 2T.
8A constant torque of 15 N m acts on a wheel as it rotates through an angular displacement of 4.0 revolutions. How much work is done by the torque on the wheel?
A.377 J
B.60 J
C.188 J
D.754 J
Explanation: Work done by torque is W = tau * theta, where theta must be expressed in radians. Since 1 revolution = 2*pi radians, 4.0 revolutions = 8*pi radians approx 25.13 rad. Thus, W = 15 * 8*pi = 120*pi approx 376.99 J approx 377 J.
9Two point masses m_1 = 2.0 kg and m_2 = 6.0 kg are separated by a distance of 1.0 m on a light rigid rod. Where is the center of mass located relative to m_1?
A.0.75 m from m_1
B.0.25 m from m_1
C.0.50 m from m_1
D.0.60 m from m_1
Explanation: Placing m_1 at x = 0 and m_2 at x = 1.0 m: x_cm = (m_1*x_1 + m_2*x_2) / (m_1 + m_2) = (2.0*0 + 6.0*1.0) / (2.0 + 6.0) = 6.0 / 8.0 = 0.75 m. The center of mass is closer to the heavier mass m_2.
10A spacecraft of mass m moves from a circular Earth orbit of radius R to a higher circular orbit of radius 2R. What is the change in gravitational potential energy delta U of the Earth-spacecraft system?
A.+G*M*m / (2R)
B.-G*M*m / (2R)
C.+G*M*m / R
D.+3*G*M*m / (4R)
Explanation: Gravitational potential energy is U(r) = -G*M*m / r. The change delta U = U(2R) - U(R) = (-G*M*m / (2R)) - (-G*M*m / R) = -G*M*m / (2R) + G*M*m / R = +G*M*m / (2R). Energy increases (becomes less negative) as radius increases.

New Zealand Scholarship Physics: Suggested Study Strategy

1Always state fundamental conservation laws (energy, linear momentum, angular momentum, charge) as the starting point for complex physical derivations.
2Pay careful attention to vector directions in rotational dynamics and electromagnetic induction scenarios.
3In AC circuits, remember that total impedance depends vectorially on resistance and reactances, not simple scalar addition.
4When solving Doppler effect problems, distinguish between moving sources (frequency shift caused by wavelength compression/expansion) and moving observers (frequency shift caused by relative wave speed).
5Verify units and order-of-magnitude estimates in modern physics calculations involving Planck's constant and atomic mass units.
