Welcome to our website darasahuru.co.tz, in this post you will find Physics Form One Notes (Ordinary Level) - All Topics, Introduction to physics, introduction to laboratory practice, measurement, force, pressure, structures and properties of matter, work, energy and power, light, Archimedes' principle and the law of floatation.
What is physics?
Physics is the branch of science concerned with the nature and properties of matter and energy.
The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.
Matter is anything that has weight and occupies space. There are three states of matter
BRANCHES OF PHYSICS
1. Acoustics – the study of sound and sound waves
2. Astronomy – the study of universe
3. Biophysics – the study of physics in living things
4. Electronics – the study of flow of electrons in the circuit
5. Geophysics – the study of physical properties of the earth
6. Mechanics – the study of motion of bodies
7. Optics – the study of light and its properties
8. Electromagnetism - This is the study of electrical and magnetic fields

Applications of Physics in Real Life
The knowledge of physics is applied in different areas like homes, hospitals, banks, industries, airports, communications, etc.
1. At home
All tools and machines used at home are made by using physics: For example, Crowbars, Hammers, door handles, cutlery, hinges, car jack, pulleys, TV, radio, iron etc.
2. In medical field
Machines such laser, x-ray, incubators, ultrasound and infrared machines are invented by Physicists
Proper handling and correct use of these machines are based on the knowledge and skills acquired in Physics.
3. Source of energy
All sources of the earth energies are explained in physics, For example Batteries and generators provide electrical energy bulbs they provide light energy
4. In transport
All vessels used in transportation are the results of the concept of physics. For Example, cars, ships, aeroplane, trains etc.
5. In communication
All devices used in communication systems are the results of concept of physics. For Example, telephones, modems, television, cables etc.
6. In entertainment
Physics enable people to enjoy a variety of leisure activities, games and photographic films, for example, digital appliances, exercise machines and other sport equipment.
7. In industry
Physicists have been able to come up with tools and process that have resulted in advanced technological equipment and new discoveries.
8. In schools
The instruments and apparatus used in school laboratories are made through the application of physics principles.
Importance of studying physics
1. It enables us answer different questions about physical properties of matter, e.g. why the ship floats on the sea while a small stone sinks?
2. It enables people to acquire skills that are required in different professions like engineering, teaching etc.
3. It is used in manufacturing different items which are useful in our daily life, e.g. electric devices, machines, etc.
4. Physics develop a logical and numerate mind.
5. Physics makes our work easier for instance, use of cars, aero planes, washing machines, calculators etc.
