In physics, energy (Greek: ἐνέργεια energeia "activity, operation") is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.
The total energy contained in an object is identified with its mass, and energy (like mass), cannot be created or destroyed. When matter (ordinary material particles) is changed into energy (such as energy of motion, or into radiation), the mass of the system does not change through the transformation process. However, there may be mechanistic limits as to how much of the matter in an object may be changed into other types of energy and thus into work, on other systems. Energy, like mass, is a scalar physical quantity. In the International System of Units (SI), energy is measured in joules, but in many fields other units, such as kilowatt-hours and kilocalories, are customary. All of these units translate to units of work, which is always defined in terms of forces and the distances that the forces act through.
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
