No. If it moves, it has kinetic energy.

This form of energy results from the fact that there is the potential for the wrecking ball to do work.
kinetic energy and potential kinetic energy decrease because a) the air is resisting the swinging item, so the item needs more energy (that it doesn't have) to continue swinging at its starting speed; and b) gravity is pulling it towards the earth. gravity is stronger than the small amount of energy put into the swinging item.
Newton's Gravity is an example of potential energy, E= -mGM/r and Planck's Energy is an example of potential energy E = hf = hc/r.
Primarily potential energy (possibly a little bit of kinetic energy if it is swinging back and forth). If whatever it is hanging by is severed, it will fall - transitioning from potential to kinetic energy.

1) at the top of the swing, the swinging object has all potential energy and no kinetic energy (no speed at that moment) while at the bottom there is no potential energy but a maximum in kinetic energy, so that the swinging object is fastest at the bottom.
This form of energy results from the fact that there is the potential for the wrecking ball to do work.
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.

Anything that had potential energy then converted to kinetic energy. A good example would a ball. If you are playing bowling and you are swinging the ball backwards and about to through it foward, the ball has potential energy. Once you release it, and while the ball is falling it has kinetic energy. The energy of the changes from potential to kinetic energy. Hope this helps XD
It is potential energy! (:
potential energy is stored energy so like, pulling a bow and arrow, pulling the bow back is a form of potential enegry because it's stroing energy This would be an example of elastic potential energy. Other types include gravitational potential energy, electrical potential energy and chemical potential energy.
Energy is never created or destroyed, but different forms of energy can be converted into another. For example, potential energy is the energy of position; a pendulum at the peak of its swing, or a spring tightly compressed. It can be converted into kinetic energy, for example, the pendulum swinging rapidly at the bottom of the swing, or the object propelled by the spring.
