Simple Harmonic Motion (SHM) and Periodic Motion

Introduction

• Importance of SHM and Periodic Motion.
• Understanding concepts through various examples.

Definition of Periodic Motion

• Motion of an object that repeats at equal intervals.
• Example: Earth's orbit around the Sun.
• Example: The back and forth motion of a pendulum.

Description of SHM

• SHM is a special type of periodic motion.
• The displacement of an object is proportional to its position from the equilibrium position.
• Relationship between force and displacement.

Characteristics of SHM

• Displacement is directly proportional.
• The restoring force is in the opposite direction.

Examples

• Pendulum:
  • Simple pendulum's SHM.
• Spring:
  • Object attached to a spring.

SHM and Non-SHM

• In non-SHM, the motion of the object is not consistent.
• Example: Motion of complex objects.

Comparison of Examples

• Circular Motion:
  • Motion of the Earth.
• Various Objects:
  • Discussion on examples of SHM and non-SHM.

Newton's Second Law

• Relationship between force and displacement in SHM.
• Formula to calculate force.

Conclusion

• The behavior of all objects in SHM.
• Importance of studying SHM.
• Understanding various aspects and properties of SHM.
