What type of energy possessed by a simple pendulum when it is at the mean position?

Potential energy
The type of energy possessed by a simple pendulum when it is at the mean position is: Potential energy.

What happens when a pendulum is at rest?

When the pendulum is at rest, not swinging, it hangs straight down. This position is called the “equilibrium position.” It is convenient to take this position as the reference position mentioned as the “origin” in the definition of position.

What is the mean position of a simple pendulum?

The Mean Position is the Position that is moderate between two other extreme positions. It is the Position of the Bob when the freely suspended Pendulum is at rest.

What type of energy is in pendulum?

An ideal pendulum system always contains a stable amount of mechanical energy, that is, the total of kinetic plus potential energy. As the pendulum swings back and forth, the balance between the two types of energy changes constantly. At some points in its swing, the pendulum has more kinetic energy.

What kind of energy does the Bob possess now?

The kinetic energy becomes zero, and the bob possesses only potential energy. As it moves towards point P, its potential energy decreases progressively. Accordingly, the kinetic energy increases. As the bob reaches point P, its potential energy becomes zero and the bob possesses only kinetic energy.

How do you find the energy of a simple pendulum?

Ignoring friction and other non-conservative forces, we find that in a simple pendulum, mechanical energy is conserved. The kinetic energy would be KE= ½mv2,where m is the mass of the pendulum, and v is the speed of the pendulum. At its highest point (Point A) the pendulum is momentarily motionless.

What do you mean by mean position and extreme position of a simple pendulum?

Mean position is the position of the bob when the freely suspended pendulum is at rest. Extreme position is the position of the bob at the maximum distance from the mean position.

What is the acceleration of the pendulum in SHM at the mean position and at extreme position?

When the bob is at the mean position O, the angle α=0, therefore sinα=0; hence, the tangential acceleration is zero. But at O, speed v is maximum and the centripetal acceleration v2/l is directed radially towards the point of support.

How does the energy of a simple pendulum vary as it moves from one extreme position to the other during its oscillation?

As the bob of the pendulum moves from P to O, the potential energy decreases but appears in the same magnitude as kinetic energy. Similarly as the bob of the pendulum moves from O to P or Q, the kinectic energy decreases to the extent it is converted into potential energy.
