Oscillations | MCQs

Explanation

In SHM, total energy (kinetic + potential) remains constant if no external force or damping is present.

Though kinetic and potential energy change with time, their sum stays the same throughout the motion.

Explanation

Restoring force 𝐹 = −𝑘𝑥 depends on displacement 𝑥.

At the mid position, x = 0, so restoring force is minimum (zero).

Explanation

Time period T = 1/frequency 1/0.5 = 2 seconds.

The time period is the time taken for one complete oscillation.

Explanation

Oscillatory systems gradually lose energy due to frictional forces (like air resistance or internal damping).

This damping reduces amplitude over time, preventing indefinite oscillation.

Explanation

The to and fro movement of a pendulum is called a vibration or oscillation.

It's a repeated back-and-forth motion about a central position.

Explanation

Explanation

A mass attached to a spring oscillates back and forth around an equilibrium position, following Hooke's Law.

This periodic motion with a restoring force proportional to displacement defines simple harmonic motion (SHM).

Explanation

 T = 2π√(L/g)

= 2π√(1/9.8)

≈ 2.006 s

Explanation

Explanation

In an oscillating LC circuit, the maximum energy stored in the capacitor during one cycle is equal to the total stored energy (U) in the circuit.

This is because the total energy oscillates between the capacitor and the inductor, with the total energy remaining constant in an ideal, lossless LC circuit.
