In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.
Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.
A village in a distand land
Calling thier name
The spirit of the jemba drum
Guiding thier way
Into thier dreams the ship set sail
Bound for far away
In the search for the shores of her bay
Cape Town
Ohhhh, cape town
Rode the liberation wave
Away from the tide
Searching for a better day
Babies trapped to thier sound
Not knowing where the ship would sail
Faith was all they had
And they finally found thier way home
To the land of love and freedom
To the place where we belong
Truth and reconciliation
Is what's going on
It's a time for celebration
The night has just begun
So dance in the light of the land
That they call cape town
MUSIC.....
It's the land of love and freedom
To the place where we belong
Truth and reconciliation
It's what's going on
It's a time for celebration
The night has just begun
So dance in the light of the land of the sun
To the land of love and freedom
To the place where we belong
Truth and reconciliation
Is what's going on
It's a time for celebration
The night has just begun
So dance in the light of the land
That they call cape town
