Physics - ICS Part 1 Physics Chapter 7 Short Questions Test

Question # 1

Explain relation between total energy, potential energy and kinetic energy for a body in simple harmonic motion.

  • Ans 1: When the K.E of the mass is maximum, the p.e of the spring is zero. Conversely, when the P.E of the spring is maximum, the K.E of the mass is zero. The interchange occurs continuously from one form to the other but the total energy remains conserved.

Question # 1

Define (a) resonance (b) damping

  • Ans 1: Resonance: When the frequency of the applied force is equal to the natural frequency of simple harmonic oscillator, the periodic amplitude of the motion may become extraordinary large. This phenomenon is called resonance.
    Damping: The oscillations in which the amplitude decreases steadily with time are called damped oscillations and this phenomenon is called damping
