Question

The type of energy possessed by a simple pendulum, when it is at the mean position is: (a) Kinetic energy (b) Potential energy (c) Kinetic + Potential energy (d) Sound energy ​

Answer 1

Answer:

The Potential Energy of the object at a height of 1m above the ground is given in a similar fashion. By definition, the change in Potential Energy is equivalent to the change in Kinetic Energy. The initial KE of the object is 0, because it is at rest. Hence the final Kinetic Energy is equal to the change in KE.

Answer 2

Answer: a) Kinetic energy.

Explanation:

As you see in the image below, the mean position of the pendulum is its lowest point. Now we know that energy will be conserved beaucase of the law of conservation of energy. This means that at the extreme position, the pendulum will have maximum potential energy. As the pendulum swings down, its potential energy will decrease and its kinetic will increase.So if it is at the mean position all the potential energy will be converted into kinetic energy. So the answer is KINETIC ENERGY
