CIE A level Physics Oscillations Quiz

What is the equation for the period of a simple harmonic motion?

• T = 2π√(m/k)

• T = 2π√(k/m)

• T = 2π(m/k)

• T = 2√(m/k)

What is the relationship between the frequency and the period of a simple harmonic motion?

• Unrelated

• Direct

• Inverse

• Constant

What factors affect the damping of oscillations?

• Sound, light, and electricity

• Air resistance, friction, and material of the oscillating object

• Color, size, and shape

• Temperature, pressure, and humidity

Explain the concept of critical damping in damped oscillations.

• Critical damping is when the oscillations continue indefinitely without any damping force.

• Critical damping is when the damping force is too weak to bring the system to rest, causing it to oscillate indefinitely.

• Critical damping is when the damping force is so strong that it causes the system to oscillate at a higher frequency.

• Critical damping is when the damping force is just enough to bring the system to rest without oscillating.

What is the equation for the driving frequency in forced oscillations?

• f = f_d

• f = f_d - 1

• f = f_d^2

• f = 2f_d

How does the amplitude of an oscillating system change with the driving frequency in forced oscillations?

• The amplitude increases until resonance frequency and then decreases

• The amplitude remains constant at all frequencies

• The amplitude increases as the driving frequency decreases

• The amplitude decreases as the driving frequency increases

What is resonance in oscillations?

• Small amplitude oscillation

• No oscillation at all

• Constant frequency oscillation

• Large amplitude oscillation

Explain how resonance can be beneficial in certain applications.

• Decreasing vibrations and hindering communication

• Amplifying vibrations and improving communication

• Creating instability and causing damage

• Causing destructive interference and reducing efficiency

What factors affect the period of a pendulum?

• Speed, time, and distance

• Length, gravity, and angle of displacement

• Color, temperature, and material

• Volume, pressure, and density

How does the length of a pendulum affect its oscillation period?

• The oscillation period increases as the length of the pendulum increases.

• The oscillation period decreases as the length of the pendulum decreases.

• The oscillation period remains constant regardless of the length of the pendulum.

• The length of the pendulum has no effect on its oscillation period.
