Shm

Question 1

What are the conditions for shm?

Answer 1

• The acceleration must be directly proportional to its displacement from the equilibrium position & act towards the equilibrium position

Question 2

What is acceleration in terms of w&x?

Answer 2

A = - w^2)x

Question 3

What does the-ve sign in a=- w^2x show?

Answer 3

The direction of acceleration is always towards the equilibrium position, in the apposite direction to the displacement

Question 4

How does the period affect the amplitude of the oscillations?

Answer 4

It doesn’t. Shm has isochronous oscillations, so the period is independent of the amplitude
