What is the definition of SHM?
periodic motion without loss of energy in which the acceleration of a body is directly proportional to its displacement and is directed towards the equilibrium position but in opposite direction of the displacement.
periodic motion without loss of energy in which the acceleration is directly proportional to its velocity and is directed towards the equilibrium position but in opposite direction of the velocity.
periodic motion without loss of energy in which the acceleration of a body is inversely proportional to its displacement
periodic motion without loss of energy in which the angular frequency is directly proportional to its displacement and is directed towards the equilibrium position but in opposite direction of the displacement.
What are the two requirements for a simple harmonic oscillator?
The object vibrates about the equilibrium point and the restoring force is proportional to the displacement
The object moves left to right and the restoring force is proportional to the displacement
The object vibrates about the equilibrium and the restoring force is greater than the displacement
The object moves left to right and the restoring force is greater than the displacement
When is a pendulum in simple harmonic motion?
