What is Physics

PHYSICS: This is the branch science which deals with the study of matter, energy and the mutual interaction between them.

This is the branch of science which deals with the study of matter in relation to energy

This is the study of matter in relation to energy.

MATTER: Is any this that has mass and occupies space.

ENERGY: Is the ability of doing work.

SCIENCE: Is the systematic study of nature.

A person who studies physics is called a Physicist.

RELATIONSHIP BETWEEN PHYSICS AND OTHER SUBJECTS

Physics, Chemistry and Biology are all natural sciences. Physics is taken to be the most fundamental of the natural sciences. This is because; the operations of the other natural science depend on the application of physics in one way or another.

The relationship of physics with other subjects is discussed below.

1. CHEMISTRY

Devices used in studying chemistry such as Bunsen burner and centrifugal device are made from the application of physics. The study atomic physics is also very useful in chemistry.

2. BIOLOGY

Physics has simplified the study of living things. Those powerful microscopes used in studying.

Biology are made from the application of physics. Different instruments for measuring blood pressure, body temperature, etc. are also made by using physics laws.

3. GEOGRAPHY

Various devices used in geography to study weather and climate are made from applications of physics. Examples of these devices are Barometers, Thermometers, and Wind vane. Cameras and satellites have been useful in survey.

4. MATHEMATICS

Physics laws are usually simplified by using mathematical expressions.

Thus, Mathematics is the language used by physicists to simplify calculations and expressions.

5. HISTORY

The study of radioactivity in physics has enabled the use of carbon-14 to determine dates in Historical excavation.

IMPORTANCE OF STUDYING PHYSICS

1. Physics help us to know the physical properties of matter.

2. Physics helps the communication to be easier.

3. Physics help us to simplify work through the use of simple machine.

4. Study of physics comes with pleasure to the person studying it.

5. The study of physics enables people to acquire skills that are required in different professions. Such as engineering, teaching, architecture, nursing, doctoring, etc.

6. The study of physics imparts knowledge that is applied in designing and manufacturing different items.

Example dry cells, simple machines, mobile phones.
