Question

When a body moves in a simple harmonic motion, its acceleration at the ends of its path is:____.

a. zero
b. less than at equilibrium
c. more than g
d. maximum

Answer 1

In simple harmonic motion, the acceleration of a body at the ends of its path is maximum. Hence the correct answer is option D

Step-by-step explanation:

In simple harmonic motion, the acceleration of a body at the ends of its path is maximum.

At the ends of its path, the body has reached its maximum displacement and is changing direction. This change in direction requires a high acceleration, resulting in the maximum acceleration at the ends of the path.

For example, if we consider an object attached to a spring and undergoing simple harmonic motion, when the object is at its maximum displacement from the equilibrium position, it experiences the maximum acceleration as it changes its direction back towards the equilibrium position.

Hence the correct answer is option D
