4. What is SHM.
 A motion in which acceleration is directly
proportional to the displacement and is
directed towards the mean position
 a ∝ x
 a ∝ -x

5. Examples Of SHM
 Horizontal Mass Spring System
 Simple Pendulum

6. Horizontal Mass Spring
System
 Let we consider a mass spring system.
One side of spring attached with hard rigid
body and other side with mass “ m ”.

7. Hook’s Law
 Force that is applied to spring is directly
proportional to the displacement.
 If the spring is un stretched, there is no net
force on the mass or the system is in
equilibrium.
 If the mass is displaced from equilibrium,
the spring will exert a restoring force, which
is a force that tends to restore it to the
equilibrium position.
F = -kx

9. Simple Pendulum
 Consider we have a string (Not Flexible)
with attached with a mass “ A “. And other
side with a hard rigid body.
 When pulled to one side of its equilibrium
position A to the position B through a small
angle θ and released, it starts oscillating to
and fro over the small

10. Factors OF SP
 Oscillation
 Equilibrium position
 Amplitude
 Time Period
 Frequency

11. Oscillation
 OSCILLATION IS THE TO AND FRO MOTION
OF THE PENDULUM ABOUT A FIXED POINT.
 THE BOB COMPLETES ONE OSCILLATION
WHEN IT SWINGS FROM ‘O’ TO ‘B’ THEN
TO ‘A’ AND RETURNS TO ‘O’.
A BO

12.  Equilibrium Position: When the pendulum is
at rest ,it is said to be in equilibrium .The
position of the pendulum at rest
 Amplitude: The maximum displacement of the
bob from the equilibrium position.
 Time Period: The time taken for complete one
oscillation
 Frequency: Frequency is the number of
oscillations per second
