1a. Motion of a body repeats in regular intervals of time is known as periodic motion.
Example: a swing in a motion, vibrating tuning fork.
1.b A periodic motion ofa body in which acceleration of a body is directly proportional to negative displacement in it is called simple harmonic motion
examples: motion of simple pendulum, oscillating spring
1c. No.
a body is in uniform circular motion is periodic but not simple harmonic motion, because acceleration is not directly proportional to negative displacement.
1d. When the springs are joined in series effective sping constant decreases. So it experiences much force.
1e. When the springs are joined in parrallel effective spring constant increases. So it has a greater stength.
