Oscillations

Which of the following statements best describes the restoring force in Simple Harmonic Motion (SHM)?

A simple harmonic oscillator has a frequency of 2 Hz. What is its period?

An object oscillates with a period of 4 seconds. What is its angular frequency?

A mass of 2 kg is attached to a spring with a spring constant of 8 N/m. What is the period of oscillation of this spring-mass system?

A mass $m$ is attached to a spring with spring constant $k$. If the mass is doubled and the spring constant is doubled, what happens to the period of oscillation?

Two identical springs with spring constant $k$ are connected to a mass $m$ in series. What is the period of oscillation of this system?

A simple pendulum has a length of 1 meter. What is its period of oscillation on Earth (where g ≈ 9.8 m/s²)?

A simple pendulum has a length $L$ and a period $T$ on Earth. If the length is quadrupled, what is the new period?

A simple pendulum has a length of 1 meter and is moved to a planet where the acceleration due to gravity is 4 times that of Earth. What is the new period of the pendulum?

Which of the following factors affects the period of a simple pendulum but NOT the period of a spring-mass system?
