What do you mean by energy? …

Power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
All moving things have kinetic energy. It is energy possessed by an object due to its motion or movement. These include very large things, like planets, and very small ones, like atoms. The heavier a thing is, and the faster it moves, the more Kinetic energy it has.
Potential energy is the stored energy of an object. It is the energy by virtue of an object's position relative to other objects. Potential energy is often associated with restoring forces such as a spring or the force of gravity
Examples of kinetic and potensial energy are:
KINETIC ENERGY
1. An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
2. A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity.
3. A downhill skier traveling down a hill has a large amount of kinetic energy because of their mass and high velocity.
4. A golf ball sitting on a tee before it is struck has zero kinetic energy because its velocity is zero.
POTENSIAL ENERGY
1. A rock sitting at the edge of a cliff has potential energy. If the rock falls, the potential energy will be converted to kinetic energy.
2. Tree branches high up in a tree have potential energy because they can fall to the ground.
3. A stick of dynamite has chemical potential energy that would be released when the activation energy from the fuse comes into contact with the chemicals.
4. The food we eat has chemical potential energy because as our body digests it, it provides us with energy for basic metabolism.
