• "Simple harmonic motion occurs when the net force is directly proportional to the displacement from the mean position and is always directed towards the mean position".
• Important physics class 10th chapter 1 notes for all students of Punjab  Textbook Board.
• In other words, when an object oscillates about a fixed position (mean position) such that its acceleration is directly proportional to its displacement from the mean position and is always directed towards the mean position, its motion is called SHM.
• Important physics notes class 10 chapter 1 for all students of Punjab  Textbook Board.
• Important features of SHM are summarized as:
• A body executing SHM always vibrates about a fixed position.
• Its acceleration is always directed towards the mean position.
• Important physics notes for class 10 chapter 1 numericals for all students of Punjab  Textbook Board.
• The magnitude of acceleration is always directly proportional to its displacement from the mean position i.e., acceleration will be zero at the mean position while it will be maximum at the extreme positions.
• Important simple harmonic motion class 10 notes pdf for all students of Punjab  Textbook Board.
• Its velocity is maximum at the mean position and zero at the extreme positions.
• Now we discuss different terms which characterize simple harmonic motion.
• Important 10th class physics chapter 10 mcqs for all students of Punjab  Textbook Board.
• Vibration: One complete round trip of a vibrating body about its mean position is called one vibration.
• Time Period (T): The time taken by a vibrating body to complete one vibration is called time period.
• Important 10th class physics chapter 10 review questions for all students of Punjab  Textbook Board.
• Frequency ( f ): The number of vibrations or cycles of a vibrating body in one second is called its frequency. It is reciprocal of time period i.e., f = 1/T
• Important 10th class physics chapter 10 numericals solved for all students of Punjab  Textbook Board.
• Amplitude (A): The maximum displacement of a vibrating body on either side from its mean position is called its amplitude.
• DAMPED OSCILLATIONS: Vibratory motion of ideal systems in the absence of any friction or resistance continues indefinitely under the action of a restoring force. 
• Important 10th class physics chapter 10 notes for all students of Punjab  Textbook Board.
• Practically, in all systems, the force of friction retards the motion, so the systems do not oscillate indefinitely. The friction reduces the mechanical energy of the system as time passes, and the motion is said to be damped. This damping progressively reduces the amplitude of the vibration of motion.

• "The oscillations of a system in the presence of some resistive force are damped oscillations".
