INTRODUCTION TO PHYSICS

  introduction to physics Physics falls under a broader category of Science. Science is divided into three areas namely Biology, Physics and Chemistry. The main objective of these subjects is to study and try to understand the universe and everything in it. What is physics? Physics is the branch of science which deals with matter and its relation to energy. It involves study of physical and natural phenomena around us. Examples of these phenomena are formation of rainbow, occurrence eclipse, the fall of things from up to down, the cause of sunset and sunrise, formation of shadow and many more. Physics as a subject is divided into six broad branches as discussed below. i) Mechanics This branch deals majorly with motions under the influence of forces. Under this branch, we look into details the aspects of linear, circular and oscillatory motions as well as motion of fluids ii) Geometrical Optics This branch takes a keen look at the behavior of light in various media. iii) Electricity and

TOPIC 1:  STATIC ELECTRICITY Concept of Static Electricity The Concept of Static Electricity Explain the concept of static electricity Static electricity refers to the accumulation of electric charges on the surface of an object. These charges are in a stationary state (at rest). The study of electric chargers at rest is known as electrostatics. It studies about the charges at stationary state. These charges can be moved away from the object y means of electric current when connected to the circuit. The Orign of Charges Explain the origin of charges The knowledge of static electricity came as early as the 6 th  century BC (600 BC). It was first discovered by the Greek ancients who rubbed amber and observed that it was able to carry attract dusts and leaves. During those times they believed that there are charges which make two things repel or attract each other. Therefore, people knew about charges as result of rubbing process
