ADDITIONAL NOTES
ENERGY is the ability to do work. The energy that we use can exist in different forms.
KINETIC ENERGY
Is related to motion of waves, electrons, atoms, molecules substances and objects
ELECTRICAL ENERGY
Is the movement of electric charges. Electric charges that move through a wire is called electricity. Lightning is another example of electrical energy
THERMAL ENERGY
Is the internal energy in substances due to the vibration and movement of the atoms and molecules within substances. Geothermal energy is an example of thermal energy
MOTION ENERGY
Is the movement of objects and substances from one place to another. Objects and substances move when a force is applied. Wind is an example of motion energy
SOUND ENERGY
Is the movement of energy through substances. Sound is produced when a force causes an object or substance to vibrate
POTENTIAL ENERGT
Is the energy that is stored and related to the position of something
CHEMICAL ENERGY
Is the energy stored in the bonds of atoms and molecules. It is the energy that holds these particles together. Biomass, petroleum, natural
13
gas and propane are examples of stored chemical energy
MECHANICAL ENERGY
Is the energy stored in objects by the application of the force. Compressed springs and stretched rubber bands are examples of stored mechanical energy
NUCLEAR ENERGY
Is the energy stored in the nucleus of an atom. It is the energy that holds the nucleus together. Nuclear power plants split the nuclei of uranium atoms is a process called fission that releases energy
GRAVITIONAL ENERGY
Is the energy of position or place. A rock at the top of a hill contains gravitational potential energy. Hydropower, such as water in a reservoir behind a dam, is an example of gravitational potential energy
Transformation of energy always follow the Law of Conservation of Energy which states that :
Energy cannot be created or destroyed Energy can be changed from one form to another When energy changes its form, the total amount
of energy is constant.
Examples of the transformation of energy found around us :
The chemical energy stored in petrol is
14
CAR
converted into heat in a car engine. This heat energy is used to move the mechanical parts of the car so it can move. Thus, chemical energy is converted into kinetic energy
FAN
Electrical energy is transformed into kinetic energy to turn the blades of the fan
FLASHLIGHT
Stored energy in a flashlight’s battery becomes light energy when the flashlight is turned on
IRON
Electrical energy is used to heat a coil and transforms into heat energy
RADIO
Electrical energy is transformed into sound energy through the speakers
15
Chemical energy heat energy kinetic energy
Chemical energy kinetic energy
Chemical energy light energy
Electrical energy heat energy

TELEPHONE
When you talk on the phone, your voice is transformed into electrical energy which passes over wires. The phone on the other end changes the electrical energy into sound through the speaker
TELEVISION
A television changes electrical energy into light and sound energy
TOASTER
A toaster changes electrical energy into heat and light energy
16
Electrical energy sound energy

ADDITIONAL NOTES
PHASES OF THE MOON is the revolution of the Moon around the Earth makes the Moon seems to change its shape in the night sky. This is caused by the different angles we see from the bright
part of the Moon’s surface called ‘phases’. The Moon goes through
22
four major shapes during cycle that repeats itself every 28 days. These phases follow the sequence of their occurrence.
NEW MOON
Part of the Moon which is not illuminated faces the Earth. The Moon is not visible. The lighted side of the Moon faces away from the Earth. This means that the Sun, the Earth and the Moon are almost in a straight line, with the Moon in between the Sun and the Earth.
CRESCENT MOON
The moon is less than half illuminated by the Sun. the fraction of the Moon’s disc that is illuminated increases. This Moon can be seen after the new Moon, but before the first quarter Moon. The crescent will grow larger and larger everyday, until it looks like the first quarter Moon.
HALF MOON
Half of the illuminated side of the Moon is visible. The fraction of the Moon’s disc that is illuminated increases. The right half of the Moon appears lighted and the left side of the Moon appears dark. During the time between the new Moon and the first quarter Moon, the part of the Moon that appears lighted gets larger and larger everyday, and continues to grow until it reaches the full Moon.
FULL MOON
The Moon’s illuminated side is visible. The lighted side of the Moon faces the Earth. This means that the Earth, the Sun, and the Moon are nearly in a straight line, with the Earth in the middle. The Moon that we see is very bright because it reflects sunlight.

THERMINOLOGY
1 Base area The extent or measurement of the lowest part of any object, on which it rests
2 Centre of The point where the weight of the object
25
gravity appears to be concentrated
3 Cone A solid or hollow object with a circular flat base and sides that slopes up to a point
4 Cube A solid or hollow object with six equal square sides
5 Cuboid A solid or hollow object which has six rectangular faces at right angles to each other
6 Cylinder A solid or hollow object with straight parallel sides and a circular or oval base
7 Energy The ability to do work
8 Hemisphere A half of sphere
9 Pyramid A hollow or solid object with a square or triangular flat base and sides that slope up to point
10
Sphere A round solid figure in which every point on the surface is of equal distance from the centre
11
Stability It is concerned with an object’s ability to return to the way it was before if disturbed
12
Strength The ability to support mass
13
Structure A building or anything that is constructed from several parts
26
ADDITIONAL NOTES
STABILITY can be defined as the ability of objects to return to its original state if disturbed. If an objects is more stable, it can be
able to resist larger forces. Objects that are stable will not topple over because they have their weight concentrated low down. This
point called the centre of gravity and the lower it is, the more stable is the object.
STRENGTH OF STRUCTURES is the ability to resists stress and strength put on the structure. Bending, compression, tension, vibration and turbulence are some of the stressed that structures
withstand. Factors that affect the strength of a structure include the types of materials used, its length, the cross sectional area or shape, how the structure is placed, weathering environment such as high
or low temperature, humidity and others.
Examples of everyday life situations used to explain how base area and height effect the stability of a structure :
Base Area
A heavyweight lifter spreads his legs to add stability
The wide distance between the wheels of a racing car is to increase the base area of the car in order to maintain its stability when it is moving fast
Laboratory apparatus such as conical flask and tripod stand has a wide base for the purpose of stability
27
A raft is more stable than a kayak because a kayak has less base area
Height
Big animals such as elephant and rhinoceros have short legs to lower the centre of gravity for stability
Racing cars are designed with low bodies to lower the centre of gravity
Boat passengers are advised to sit when the boat moves for stability
