When is a pendulum in simple harmonic motion?

• Never

• All the time

• only at large angles

• only at small angles

When is the pendulum at maximum velocity

• At its lowest point

• At its highest point

• It moves at a constant velocity

• It is at rest

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.
