(b) Give Examples of simple harmonic motion from daily life
Ans. (a) Characteristics Of SHM
The following are the main characteristics of SHM
i. SHM is a vibratory motion.
ii. Acceleration of body during SHM is always directed towards mean position
iii. acceleration of body during SHM is directly proportional to is displacement form mean position
iv. The acceleration is maximum at extreme position and its zero at mean position.
v. The speed or K.E is maximum at mean position and zero at extreme position
vi. The P.E is maximum at extreme position and zero at mean position
vii. Total energy of body during its SHM remains constant.
viii. Amplitude of oscillation for SHM remains constant,
Ans. (b) Daily Life Examples of Simple Harmonic Motion (SHM)
SHM is an ideal vibratory motion. Following are the nearest examples.
i. an oscillating simple pendulum with small amplitude
ii. An oscillating mass-spring system
iii. the motion of a ball and bowl system
iv. The motion of the prong of tuning fork
