Q (5) Define simple harmonic motion prove that vibrating
motion of mass attached to a spring is SHM? A simple
pendulum complete one vibrating in 2 seconds calculate
its length when g =10 ms-2?
ANSWER : Part (A) Simple harmonic motion: Definition:
Simple harmonic motion is occurs when the net force is
proportional to the displacement from mean position
and is always directed is towards mean position. Motion
of mass attached to spring one of simplest motion is
horizontal mass spring system as shown in figure.If the
spring is compressed specked though the small
displacement from x its mean position it exerts a force i
on mass. By hooks law:e The force is directly
proportional to the change in length x of spring [f=- kx]
when x is displacement of mass from mean position k is
spring constant. Spring constant: k = f (nm-1) x It is the
ratio of force to change in length. It i measure of stiffness
of spring. Stiff spring have larger k and soft spring have
