## FAQs on Simple Harmonic Motion: Velocity, Acceleration & Energy Video Lecture - Physics Class 11 - NEET

 1. What is simple harmonic motion?
Ans. Simple harmonic motion is a type of periodic motion where an object oscillates back and forth around an equilibrium position. The motion is called "simple" because the restoring force acting on the object is directly proportional to its displacement from the equilibrium position.
 2. How is velocity related to simple harmonic motion?
Ans. In simple harmonic motion, the velocity of the object is constantly changing as it oscillates. At the equilibrium position, the velocity is maximum, while at the maximum displacement from the equilibrium position, the velocity is zero. The velocity is directly proportional to the displacement from the equilibrium position.
 3. What is the acceleration in simple harmonic motion?
Ans. The acceleration in simple harmonic motion is also constantly changing. At the equilibrium position, the acceleration is zero, while at the maximum displacement, the acceleration is maximum. The acceleration is directly proportional to the displacement and is directed towards the equilibrium position.
 4. How is energy related to simple harmonic motion?
Ans. In simple harmonic motion, the total mechanical energy of the system is conserved. It is the sum of the kinetic energy and potential energy. As the object oscillates, the energy is continuously converted between kinetic and potential energy, but the total energy remains constant.
 5. How can the period of a simple harmonic motion be calculated?
Ans. The period of a simple harmonic motion can be calculated using the formula T = 2π√(m/k), where T represents the period, m is the mass of the object, and k is the spring constant. The period is the time taken for one complete cycle of oscillation.
