What is K in Pendulum?


Open in App
Solution

  1. The term k in the case of a simple pendulum represents the spring constant.
  2. Spring constant is the property of the spring.
  3. The simple harmonic motion of a simple pendulum occurs when the displacement and the restoring force are proportional.
  4. From Hooke's law, the equation of the SHM of a simple pendulum can be written as F=-kx where F is the restoring force, x is the displacement, k is the spring constant.
  5. Applying newtons second law, the equation becomes
    F=-kx=ma
    where m is the mass, a is the acceleration.
  6. The spring constant can be expressed as : k=mgL, where L is the length, m is the mass, and g is the acceleration due to gravity.

Hence, K represents the spring constant.
