Questions and Answers

What does the elastic constant (k) represent in Hooke's Law?

  • The rate of acceleration of the object.
  • The maximum displacement of the object.
  • The relationship between force and displacement. (correct)
  • The inertia of the object.

When does an object exceed its elastic limit?

  • When its acceleration becomes zero.
  • When the applied force is large enough and it doesn't return to its original state. (correct)
  • When its potential energy is at a maximum.

Study Notes

Hooke's Law

  • The restoring force (F) is proportional to the displacement (s) from its equilibrium position.
  • The restoring force is in the opposite direction to the displacement.
  • F = –ks, where k is the elastic constant.

Elastic Constant

  • The elastic constant (k) is the constant of proportionality relating force and displacement in Hooke's Law.
  • The unit of k is newton per metre (N m-1).

Simple Harmonic Motion (SHM)

  • SHM is the periodic motion in which the acceleration of a body is proportional to the displacement of that body from its equilibrium position and directed towards that position.
  • A body is in SHM if:
    • Its acceleration is directly proportional to its distance from a fixed point on its path.
    • Its acceleration is always directed towards that point.

Characteristics of SHM

  • The potential energy is converted into kinetic energy and vice versa during SHM.
  • Examples of SHM include:
    • A mass on the end of a spring or elastic band.
    • The rise and fall of the tide.
    • The prongs of a tuning fork when struck.

Oscillations and Amplitude

  • A cycle or an oscillation is the movement from a particular position back to that same position.
  • Amplitude (A) is the maximum distance that an object moves from its equilibrium position.
