Want this question answered?
There is Mechanical Energy. This Mechanical Energy equals Potential + Kinetic Energies. At the maximum heigh and with the pendulum set still there is the maximum Potential Energy (so Kinetic equals 0, and Potential Energy equals Mechanical Energy). When we release the pendulum this Potential Energy transforms into Kinetic Energy which will be maximum and equal to the Mechanical Energy when the 'rope' or 'string' that holds the pendulum is in the same direction as the acceleration, or force, in this case gravity. Then, and if there is no friction (e.g. air) the pendulum will reach the same maximum heigh that it had in X0 and the Kinetic Energy will transform into Potential, reinitiating the process but in the opposite direction. Hope i helped and sorry for my english. :)
A pendulum swings back and forth with a period based on its length. When it is pointing directly down, moving horizontally with maximum speed, there is no potential energy; all the energy is kinetic. When it is maximally away from this position it has stopped and so has no kinetic energy; all the energy is potential. Thus at any one time there is the same amount of energy in a swinging pendulum but depending on where it is in its arc of motion there will be different amounts of kinetic and potential energy.
A pendulum oscillates between two stationary points at the ends of its swing, with maximum speed at the center of the swing. So the kinetic energy is highest at the swing center where it is travelling fastest, and drops to zero at the stationary end points. The potential energy does the opposite, being a maximum at the ends and minimum in the center.
When the bob is in the both extreme positions.
There are 3 Points at which the pendulum significantly changes direction. First it starts off pulled back before it is released it has a high potential energy because it is higher from the source of gravitation (generally the earth) but has no kinetic energy because it is not moving. Once released the pendulum loses potential energy and it swings downward and gains kinetic energy as it speed up. At the bottom of its swing it is going as fast as it will and has the highest kinetic energy and the lowest potential energy, then as it rises it loses the kinetic energy because it has to fight against gravity and loses kinetic energy and gains potential energy as it rises. And it repeats itself. One important thing to note is this is a great application of the law of conservation of energy because as it loses potential energy it gains the same energy in kinetic energy and vice versa (not counting the effects of wind resistance and friction however minor).
As the pendulum stops swinging, its maximum kinetic energy (the initial energy at the beginning of the swing) decreases, and its potential energy increases. Once the pendulum stops, it will have zero kinetic energy and maximum potential energy.

If a pendulum is at its center position, then there are two possibilities: 1). It may be swinging. Then its kinetic energy is maximum and its potential energy is zero. 2). It may be stopped altogether. Then it has no energy at all.
This question makes sense in the context of something like a pendulum. At the top of its swing, a pendulum is at maximum height, is not moving and so has zero kinetic energy, and has maximum potential energy since all its energy is potential. As it falls, it gradually moves with increasing speed, so its potential energy is being converted to kinetic energy. At the bottom of the swing, it is moving at maximum speed, and all its energy is kinetic, none is potential, Then it starts to move upwards again, and its kinetic energy is gradually converted back to potential energy.
At the low point of a swinging pendulum, the type of energy being demonstrated is maximum kinetic energy. It has zero potential energy at this point of the swing.

When the pendulum is at its lowest point, it has the least potential energy. Therefore, logically, due to conservation of energy, its kinetic energy is at its maximum. Therefore its speed is also at its maximum, as well as its momentum (velocity x mass).

At the bottom of it's swing. This is because it has accelerated to it's peak velocity due to gravity.
Maximum kinetic energy occurs at the bottom of the swing. Maximum potential energy occurs at the top of the swing.
