Question

Which of the following is/are not SHM?
(1) y = Acosot
(3) y = Asin 30t
(2) y = Asinot
(4) y = Aekt​

Answer 1

Following which is not a SHM equation is option (4) y = Aekt

• We know that, simple harmonic motion is a special type of periodic motion or oscillation where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.

• Also we know that, sin and cos are also periodic function.

• Therefore, option 1, 2 and 3 are equation of SHM

• Where in option 4 that is exponential function which is not periodic in nature.

Answer 2

Answer:

option 4

Explanation:

always exponential is not a periodic function
