Conservation of Energy in a Simple Pendulum
The simple pendulum is a classic example of a system that exhibits periodic motion. When a pendulum is displaced from its equilibrium position and released, it swings back and forth, exhibiting both kinetic and potential energy.
The conservation of energy principle states that energy cannot be created or destroyed, only transformed from one form to another. In the case of a simple pendulum, the energy transformations are as follows:
1. Kinetic Energy: When the pendulum is released from a displaced position, it begins to move. At this point, it has maximum kinetic energy and minimum potential energy.
2. Potential Energy: As the pendulum reaches its highest point, it stops moving momentarily and has maximum potential energy and minimum kinetic energy.
3. Kinetic Energy: As the pendulum swings back down, it gains speed and kinetic energy while losing potential energy.
4. Potential Energy: When the pendulum reaches its lowest point, it has maximum kinetic energy and minimum potential energy.
This cycle repeats itself as the pendulum swings back and forth, with the total energy of the system remaining constant. Therefore, we can say that the conservation of energy in a simple pendulum contains both transformations of energy accordingly.
Hence, option C is the correct answer.
Which of the following statements is/are correct about the conservati...
- A swinging pendulum is an example of the conservation of energy.
- This is because a swinging simple pendulum is a body whose energy can either be potential or kinetic or a mixture of potential and kinetic. Still, its total energy at any instant time remains the same.
- The transformation of potential energy into kinetic energy and of kinetic energy into potential energy is given by a swinging simple pendulum.
Conservation of energy: - Whenever energy changes from one form to another, the total amount of energy remains constant.
- The total energy before and after transformation will be the same.
- During the conversation of energy from one form to another, some energy may be wasted.
- Still, the total energy remains the same.
