SSS 1: INTRODUCTION TO PHYSICS

-
PHYSICS is a branch of pure science that deals with the study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity, etc.
       
        Subject areas in physics
Physics as a subject is divided into the following broad branches which are 
1. Mechanics 
2. Waves 
3. Electromagnetism
4. Optics 
5. Nuclear physics 
6. Thermodynamics 

•Mechanics is a branch of physics that deals with motion under the influence of forces. This includes both bodies in motion and bodies at rest.

•Waves is a branch of physics that deals with the propagation of energy through space.

•Electromagnetism is a branch of physics that deals with the interaction of electric and magnetic fields.

•Optics is a branch of physics that deals with the behavior of light in various media such as glass and water 

•Nuclear physics deals with the behavior of particles of the nucleus and the accompanying energy changes 

•Thermodynamics deals with how heat as a form of energy is transformed into other forms of energy
                
              Fields of study in physics 
Some of the fields of study in physics in the higher institutions are 
•Geophysics 
•Nuclear physics 
•Biophysics 
•Engineering Physics 
•Astrophysics 
•Medical Physics 
•Space physics 
•Mathematics physics etc 

                 Careers in physics 
Careers in physics include 
•Physics teacher 
•Physics lecturer 
•Medical physicist 
•Optical engineer

•Laboratory manager etc

                 Importance of physics 
1. Physics helps to acquire knowledge and skills to understand how and why natural phenomena happen 
2. It generates fundamental knowledge for future technological advancements 
3. Knowledge of physics gives a better understanding of our immediate and natural environment 
4. The knowledge of physics has enhanced telecommunication through information and communication technology 
5. Knowledge of physics has helped in the design of various means of transportation.
6. Knowledge of physics has helped in the invention of modern medical equipment to improve health 

                       Assignment 
1. Who is a physicist?
2. Mention the names of twenty (20) physicists and their discoveries
