10a Oscillations Quiz physics alevel edexcel

Damped oscillation refers to:

• a) Oscillation where energy is added to the system

• b) Oscillation where energy is removed from the system

• c) Oscillation where the amplitude decreases over time due to external forces

• d) Oscillation where the amplitude increases over time due to external forces

Overdamping occurs when:

• a) Damping is insufficient to prevent oscillation

• b) Damping is excessive, preventing oscillation entirely

• c) Damping matches the natural frequency of the system

• d) Damping is unrelated to the natural frequency of the system

Critically damped oscillation occurs when:

• a) Damping is insufficient to prevent oscillation

• b) Damping is excessive, preventing oscillation entirely

• c) Damping matches the natural frequency of the system

• d) Damping is unrelated to the natural frequency of the system

The period formula of a pendulum depends on:

• a) The mass of the pendulum bob

• b) The length of the pendulum

• c) Time taken for one complete oscillation

• d) Angular displacement

Free oscillation and forced oscillation differ in that:

• a) Free oscillation occurs without any external force, while forced oscillation occurs with an external force

• b) Free oscillation occurs at the natural frequency, while forced oscillation occurs at the driving frequency

• c) Free oscillation always leads to resonance, while forced oscillation does not

• d) Free oscillation is always damped, while forced oscillation is not necessarily damped

• b) The frequency at which it oscillates without any external force

• c) The maximum frequency it can attain

• d) The minimum frequency it can attain
