Consider a block attached to a horizontal spring that undergoes simple harmonic motion as shown with an amplitude of A =10 cm

If the kinetic energy of the block is increasing the block must be

(a) moving away from the equilibrium position

(b) moving towards the equilibrium position

c) at equilibrium position

(d) maximum displacement

Homework Answers

Answer #1

At the extreme position ,the velocity of the block is zero and so the Kinetic energy is zero

At the equilibrium position , the velocity is maximum and so the kinetic energy is maximum

So, When the block move towards the equilibrium position kinetic energy is increasing and when moves away from the equilibrium position kinetic energy is decreasing

Option (b) is the correct answer

Kinetic energy is increasing when moving towards the equilibrium position.
