Question
If a body is executing simple harmonic motion, then:
- At extreme positions, the total energy is infinite
- At extreme positions, the total energy is zero
- At the equilibrium position, the total energy is in the form of kinetic energy
- At the equilibrium position, the total energy is in the form of potential energy
Hint:
It is a type of oscillatory motion in which the restoring force is directly proportional to the displacement of the body from its mean position.
The correct answer is: At the equilibrium position, the total energy is in the form of potential energy
Simple harmonic motion (SHM): It is a type of oscillatory motion in which the restoring force is directly proportional to the displacement of the body from its mean position. The energy in simple harmonic motion: The total energy of a particle executing SHM is the sum of its kinetic and potential energy.
At equilibrium position, potential energy of the body is zero. So, the total energy at equilibrium position is completely kinetic energy
