What is defined as oscillations around an equilibrium position?

• Simple harmonic motion

• Acceleration

• Frequency

• Velocity

Answer explanation

Simple harmonic motion is defined as oscillations around an equilibrium position.

In simple harmonic motion, the acceleration is proportional to the displacement but in which direction?

• Opposite direction

• No relation

• Same direction

• Perpendicular direction

Answer explanation

In simple harmonic motion, the acceleration is proportional to the displacement in the opposite direction.

What stays constant in simple harmonic motion without damping?

• Frequency

• Total energy

• Velocity

• Displacement

Answer explanation

In simple harmonic motion without damping, total energy remains constant as it oscillates between kinetic and potential energy.

The time period, frequency, and angular frequency of an oscillator are related by which equation?

• T = 2πm/k

• T = 2πl/g

• T = 1/f

• T = 2π/ω

Answer explanation

The correct equation relating time period (T) and angular frequency (ω) of an oscillator is T = 2π/ω.

Which of the following is not a main type of simple harmonic oscillator?

• Simple pendulum

• Mass attached to a string

• Mass-spring system

• Rotating wheel

Answer explanation

The rotating wheel is not a main type of simple harmonic oscillator as it does not exhibit the typical back-and-forth motion seen in simple pendulums, mass attached to a string, and mass-spring systems.

How can the time period of a simple pendulum be calculated?

• T = 1/f

• T = 2πm/k

• T = 2πl/g

• T = 2π/ω

Answer explanation

The correct formula to calculate the time period of a simple pendulum is T = 2πl/g, where T is the time period, l is the length of the pendulum, and g is the acceleration due to gravity.

What is the formula for calculating the time period of a mass-spring system?

• T = 1/f

• T = 2π/ω

• T = 2πm/k

• T = 2πl/g

Answer explanation

The correct formula for calculating the time period of a mass-spring system is T = 2πm/k, where m is the mass of the object and k is the spring constant.

What is the formula for angular frequency, ω, in simple harmonic motion?

• ω = 2π

• ω = 2π(T)

• ω = -xω^2

• ω = 1/f

Answer explanation

The correct formula for angular frequency in simple harmonic motion is ω = 2π(). This choice represents the accurate equation for angular frequency.
